Explanation:

The weight of the human heart varies between sexes. The average weight of a female heart is approximately 250-300 grams (9 to 11 ounces), while a male heart typically weighs between 300-350 grams (11 to 12 ounces). Considering these average weights, the correct answer to the question is 'b. 9-12 oz'.

The human heart is similar in size to a person's clenched fist and has a shape comparable to that of a pinecone. Due to the increased demand placed on their hearts, athletes, especially those training in aerobic sports, can experience an increase in heart size, a condition known as hypertrophy. However, not all heart enlargement is positive, as it can also indicate potential health issues like hypertrophic cardiomyopathy.
