The correct answer is (a).
Section 7 of the Indian Penal Code defines the word “gender” as follows:
“Gender” means the sex of a person, male or female.
This definition is based on the biological sex of a person, which is determined by their chromosomes. However, it is important to note that gender is not always the same as biological sex. For example, a person who is transgender may identify with a gender that is different from their biological sex.
Section 7 of the Indian Penal Code is important because it provides a definition of gender that can be used in the law. This definition is important for ensuring that the law is fair and does not discriminate against people on the basis of their gender.
The other options are incorrect because they do not provide a definition of gender.
