Not attemptedCorrect Answer: (a) 1 only
Albedo is the fraction of incident sunlight an object reflects and thus governs its apparent brightness when viewed in reflected light (statement 1 correct). Mercury’s Bond albedo (~0.12) is lower, not higher, than Earth’s average albedo (~0.30), making statement 2 incorrect. Hence only statement 1 is correct.
