Which one of the following is a correct statement about dormancy?

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.

The corner points of the feasible region determined by the following system of linear inequalities :
\(2 x+y \leq 10, \quad x+3 y \leq 15, \quad x, y \geq 0\) are \((0,0),(5,0),(3,4)\) and \((0,5)\).
Let \(z=p x+q y\), where \(p, q>0\).
Condition on \(p\) and \(q\) so that maximum of \(z\) occurs at both \((3,4)\) and \((0,5)\) is :

Identify 'X' along with oxidation state of halogen in the given reaction :
\(3\text{Cl}_2 + 6\text{NaOH} \rightarrow 5\text{NaCl}+\text{X} + 3\text{H}_2\text{O}\) (hot and conc.)

If \(\left|\begin{array}{ccc}x+4 & 2 x & 2 x \\ 2 x & x+4 & 2 x \\ 2 x & 2 x & x+4\end{array}\right|=k(x-4)^2\), then value of \(k\) is :
