Sry is best described as ) a gene present on the x chromosome that triggers female developmentb) an autosomal gene that is required for the expression of genes on the y chromosomec) a gene region present on the y chromosome that triggers male developmentd) an autosomal gene that is required for the expression of genes on the x chromosome

The correct option is C. SRY is best described as a gene region present on the Y chromosome that triggers male development.

Explanation:

SRY (sex-determining region) is a gene that is found in the Y chromosomes of males. A protein known as sex-determining region Y protein is made by the SRY gene. This protein performs important functions like the development of male sexual characteristics etc. The SRY gene is also known as testis determining factor (TDF). Hence, option C is the correct option.

Other options are false because neither the SRY gene is autosomal nor is it present on the X chromosome.
