Answer: (B)

Verified step by step guidance

1. Understand the concept of sexual reproduction: Sexual reproduction involves the combination of genetic material from two parents, resulting in offspring with genetic variation.
2. Identify the main disadvantages of sexual reproduction: Consider factors such as energy expenditure, time investment, and the need for finding a mate.
3. Evaluate the statement 'It results in offspring that are genetically identical to the parent': In sexual reproduction, offspring are genetically diverse, not identical to the parent.
4. Consider the statement 'It requires more energy and time to find a mate': Sexual reproduction often involves significant energy and time to locate and attract a mate, which is a disadvantage.
5. Analyze the statement 'It leads to less genetic diversity compared to asexual reproduction': Sexual reproduction actually increases genetic diversity, which is an advantage, not a disadvantage.
