To identify which statement is true regarding the maturation of the reproductive systems, let's go through each option:

A. Early menstrual periods are usually normal.
To determine if this statement is true, we need to understand the normal age range for the onset of menstruation. On average, girls start their menstrual cycle between the ages of 9 and 15. If early menstrual periods fall within this range, then the statement would be true. However, if "early" refers to a time before 9 years old or after 15 years old, then the statement might not be true.

B. In the first months of menstruation, girls do not usually ovulate.
To assess if this statement is true, it's important to understand the relationship between menstruation and ovulation. Menstruation occurs when an unfertilized egg that has reached maturity is not fertilized by sperm. Ovulation is the release of a mature egg from the ovary. Typically, ovulation follows after menstruation. If this statement suggests that ovulation does not occur during the first few months of menstruation, it might be true.

C. At about 17, boys have their first spontaneous ejaculation.
To evaluate the validity of this statement, we need to know the typical age range for the onset of spontaneous ejaculation in boys. Generally, spontaneous ejaculation, also known as nocturnal emissions or "wet dreams," might first occur during adolescence. However, the exact age can vary from person to person. If the statement suggests that around 17 years old is the average age for the first spontaneous ejaculation in boys, it could be true.

Based on the assessment, if you think option C is the true statement, you would be correct. However, please note that individual experiences may vary, and it is always best to consult reliable sources or healthcare professionals for a more precise understanding of reproductive maturation.
