Explanation:

Section 498A of the Indian Penal Code deals with cruelty by a husband or his relatives towards a woman. Cruelty under this section encompasses both physical and mental cruelty, often manifested as harassment, especially in connection with dowry demands or other forms of ill-treatment that cause grave injury or danger to life, limb, or health, or drive a woman to suicide. 'Harassment of woman' (D) best encapsulates the broad scope of cruelty under 498A, which is not limited to 'only' physical or mental cruelty, and 'cruelty by wife' is incorrect as the section is against the husband/relatives.
