Final Answer :
B
Explanation :
The development of facial and chest hair, pubic hair, and a deepening of the voice are all examples of secondary sex characteristics, which are traits that are influenced by hormones and develop during puberty to distinguish males from females. Primary sex characteristics refer to the development of reproductive organs, while male attachment and reproductive signaling characteristics are not recognized terms in the context of human development.
