Answer the question on the basis of passage given below :
Adsorption is a surface phenomenon which can be expressed by means of an empirical relationship know as Freundlich Adsorption isotherm. The relationship given by \(\frac{x}{m} = Kp^{\frac{1}{n}}\ (n > 1)\)
x = Mass of the gas adsorbed
m = Mass of adsorbent
p = Pressure at which adsorption takes place
K and n are constant

Gas	Critical Temperature (in K)
\(\text{C}_2\text{H}_6\)	210
\(\text{SO}_2\)	630
\(\text{Cl}_2\)	243
\(\text{H}_2\)	33

(B) Thiamine	(II) Xerophthalmia
(C) Glucocorticoids	(III) Beri-Beri
(D) Estradiol	(IV) Addison's disease

Read the passage carefully and answer the questions
Alcohols and phenols are formed when a hydrogen atom in a hydrocarbon, aliphatic and aromatic respectively is replaced by - OH group. These are further classified on the basis of number of hydroxy groups and according to the hybridization of the carbon atom \(sp ^2\) or \(sp ^3\) to which the -OH group is attached. They find applications in industry as well as in day-to-day life. One of the most commercially obtained alcohol also known as wood spirit is obtained by destructive distillation of wood. Both alcohols and phenols are acidic in nature. The acidity of alcohols and phenols vary according to the nature of substituent(s) attached to them. Alcohols and phenols react with carboxylic acids, acid chlorides and acid anhydrides to form esters. Introduction of acetyl group in alcohols and phenols is called acetylation. Phenol undergo electrophilic aromatic substitution reaction because the -OH activates the benzene ring. It undergoes nitration, halogenation and sulphonation reactions.

"The probability distribution of a random variable \(x\) is :
\(P(X=x)=\left\{\begin{array}{ll}k x^2, & \text { for } x=1,2,3 \\2 k x, & \text { for } x=4,5,6 \text { where } k \text { is a constant. } \\0, & \text { otherwise }\end{array}\right.\)
Match List-I with List-II

List I	List II
(A) k	(I) 7/22
(B) \(P(X \geq 4)\)	(II) 1/44
(C) \(P(X<4)\)	(III) 95/22
(D) E[X]	(IV) 15/22
