'Statins' function by the enzyme responsible for synthesis of cholesterol

Medical termination of pregnancy is considered relatively safe -

The corner points of the feasible region determined by the system of Linear Constraints are \((0,3),(1,2)\) and \((3,0)\). Let \(z=p x+q y\), where \(p, q>0\), be the objective function. Find the condition on \(p\) and \(q\) so that the minimum of \(z\) occurs at \((3,0)\) and \((1,2)\) :

The projection of the vector \(2 \hat{i}-\hat{j}+3 \hat{k}\) on the vector \(3 \hat{i}+2 \hat{j}+6 \hat{k}\) is :

Read the following paragraph and answer the given questions.
Cancer detection is based on biopsy and histopathological studies. 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. Do you know why mother's milk is considered very essential for the new-born infant? The yellowish fluid colostrum secreted by mother during the initial days of lactation has abundant antibodies (IgA) to protect the infant. 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 exaggerated response of the immune system to certain antigens present in the environment is called allergy. The use of drugs like anti-histamine, adrenalin and steroids quickly reduce the symptoms of allergy. Drugs like barbiturates, amphetamines, benzodiazepines, and other similar drugs, that are normally used as medicines to help patients cope with mental illnesses like depression and insomnia, are often abused. Morphine is a very effective sedative and painkiller, and is very useful in patients who have undergone surgery.
Which type of drug cannot quickly reduce the symptoms of allergy?

(B) ionisation energy will be least for Ge, followed by Si and highest for C
(C) number of free electrons for conduction in Ge and Si are negligibly small but significant for C
(D) number of free electrons for conduction in Ge and Si are significant but negligibly small for C
Choose the correct answer from the options given below:
