Assertion (A) : Venus is the brightest object in the sky after the sun. Reason (R) : Venus is the second planet from the sun in our solar system.

Both A and R are individually true and R is the correct explanation of A

Both A and R are individually true, but R is not the correct explanation of A

A is true, but R is false

A is false, but R is true

Result

Your answer: — · Correct: D

Explanation

Assertion (A) is false: The Moon is the brightest object in the sky after the Sun. Venus is the third brightest celestial object, so stating it is the brightest after the Sun is factually incorrect.

Reason (R) is true: Venus is the second planet from the Sun in our solar system, located between Mercury and Earth.

Since the assertion is false but the reason is true, the correct answer is D.
