The correct answer is B. More eggs can be fertilized at one time.
External fertilization is a reproductive strategy where fertilization occurs outside the body of the female organism. This process usually takes place in water, and both eggs and sperm are released into the environment. This method offers several advantages, such as:
1. More eggs can be fertilized at one time: Since external fertilization involves release of a large number of eggs and sperm into the water, the chances of successful fertilization are increased. This is especially important in species where the survival rate of fertilized eggs is low due to environmental factors or predation.
To deduce this answer by yourself, it is important to have a basic understanding of external fertilization and its advantages. You can reason that external fertilization allows a large number of eggs and sperm to be released simultaneously in the water. This increases the likelihood of successful fertilization, as a larger number of eggs can be potentially fertilized. This makes option B, "More eggs can be fertilized at one time," the correct choice.
