Question

ASSERTION: Atmosphere of Venus is made up of layer of H2SO4 . REASON: This layer is of white and yellowish clouds​

Answer 1

Answer:

The atmosphere of Venus is made up mainly of carbon dioxide, and thick clouds of sulfuric acid completely cover the planet. ... This greenhouse effect has made the surface and lower atmosphere of Venus one of the hottest places in the solar system

Planets have the colors that they have because of what they are made of and how their surfaces and/or atmospheres reflect and absorb sunlight. Venus is entirely covered with a thick carbon dioxide atmosphere and sulphuric acid clouds which give it a light yellowish appearance.

so i think both A and B are true
