Answer 1

The correct option is D

Secondary sexual characters include the ovary and penis

Primary sexual characteristics are present from birth and are directly concerned with reproduction and allow the differentiation of males and females. The ovary in females and penis in males are primary sexual characters. Secondary sexual characters appear during puberty due to the hormones released during this time. Primary and secondary sexual characteristics differentiate males and females in a sexually dimorphic species. Secondary sexual characteristics are not concerned with reproduction or production of gametes.
