Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Metallic character decreases and non-metallic character increases on moving from left to right in a period. Reason (R) : It is due to increase in ionisation enthalpy and decrease in electron gain enthalpy, when one moves from left to right in a period. In the light of the above statements, choose the most appropriate answer from the options given below : (A) Both (A) and (R) are correct and (R) is the correct explanation of (A). (B) (A) is false but (R) is true. (C) (A) is true but (R) is false. (D) Both (A) and (R) are correct and (R) is not the correct explanation of (A). uhps nks dFku fn, gSaA ,d dk uke vfHkdFku (A) rFkk nwljs dk dkj.k (R) gSA vfHkdFku (A) : ,d vkorZ eas cka,a ls nkfgus vksj tkus ij /kkfRod xq.k ?kVrs gSa vkSj v/kkfRod xq.k c<+rs gSaA dkj.k (R) : ,slk vkorZ esa] ck,a ls nkfgrus vksj tkus ij vk;uu ,sUFkSYih ds c<+us rFkk bysDVªkWu yfC/k ,sUFkSYih ds ?kVus ls dkj.k gksrk gS A mijksDr dFkuksa ds lanHkZ esa] lokZf/kd mfpr mÙkj fuEu fodYiksa esa ls pqfu,A (1) nksuksa (A) rFkk (R) lgh gSa vkSj (R) lgh O;k[;k gS (A) dhA (2) (A) lgh ugha gS ijUrq (R) lgh gSA (3) (A) lgh gS ijUrq (R) lgh ugha gSA (4) nksuksa (A) rFkk (R) lgh gSa vkSj (R) lgh O;k[;k ugha gS (A) dhA
