This statement correctly states that an XY combination of sex chromosomes is a genetic male, and the secretion of testosterone by the fetal gonads induces the development of male external genitalia and reproductive tract. Option A is incomplete as it only mentions the genetic makeup but doesn't provide information on the development of male characteristics. Option B is incorrect as it refers to fetal gonads inducing the development of male characteristics, not female. Option C is also incorrect for the same reason as option B. Therefore, only option D is correct. Option E is incorrect as options A, B, and C are not entirely correct.
