Reduction of nitrobenzene gives Nitrobenzene \(\left( C _6 H _5 NO _2\right) \xrightarrow{ H _2, Pd , \text { Ethanol }}\) Product

Answer the question on the basis of passage given below :
One of the notable features of the transition element is the great variety of oxidation states it may show in its compounds. The elements which give the greatest number of oxidation states occur in or near the middle of the series. Manganese, for example exhibits all the oxidation states from +2 to +7. The lesser number of oxidation states at the extreme ends is either due to losing or sharing of few electrons (Sc, Ti) or too many d electrons of higher valence. Early in the first series scandium (II) is virtually unknown and titanium (IV) which is more stable than Ti (III) or Ti (II). On the other end, the only oxidation state of zinc is \(+ 2\).
Cris reducing but Mn is oxidising in nature although both have \(d ^{ 1 }\) configuration. It is due to the reason that Cr configuration changes from

The spin magnetic moment of cobalt in the compound named Mercuric tetrathiocyanato cobaltate (II) is

The processing of pro-insulin involves:

From the binding energy per nucleon versus mass number curve :
(A) B.E/nucleon is small for light nuclei like \( {}_{1}^{1}H, {}_{1}^{2}H, {}_{1}^{3}H \)
(B) B.E/nucleon decreases in heavy nuclei making them less stable stab.
(C) When two light nuclei combine to form heavy nucleus, energy is absorbed.
(D) Heavy nucleus splits into lighter nuclei which results in liberation of energy.
Choose the correct answer from the options given below :

Read the following paragraph carefully and answer the given questions.
Certain types of leukocytes (WBC) of our body like polymorpho-nuclear leukocytes (PMNL-neutrophils) and monocytes and natural killer (type of lymphocytes) in the blood as well as macrophages in tissues can phagocytose and destroy microbes. For determining the cause of allergy, the patient is exposed to or injected with very small doses of possible allergens, and the reactions studied. The use of drugs like anti-histamine, adrenalin and steroids quickly reduce the symptoms of allergy. Heroin, commonly called smack is chemically diacetylmorphine which is a white, odourless, bitter crystalline compound. This is obtained by acetylation of morphine. Techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are very useful to detect cancers of the internal organs. Different species of Plasmodium (P. vivax, P. malaria and P. falciparum) are responsible for different types of malaria. Of these, malignant malaria caused by Plasmodium falciparum is the most serious one and can even be fatal.
Which of the following drugs are commonly used to quickly reduce the symptoms of allergy?
