Answer: The correct answer is -
D. a slight limp
Explanation:
Acquired trait is any feature that an organism develops after birth and it is non heritable that is not passed from one generation to the next generation.
On the contrary, inherited trait (such as fur color, length of ears) is present from birth and it is inherited from parents through genetic material.
Slight limp is basically uneven walking that results due to some injury in the legs or because of physical limitation. It means that it is developed after the birth.
Thus, option D) is the right answer.
