The correct answer is (a). A Hindu wife can adopt a boy and a girl simultaneously without the consent of her husband. This is because the Hindu Adoptions and Maintenance Act, 1956, does not require the consent of the husband for a Hindu wife to adopt a
child. The Act only requires the consent of the wife and the child’s guardian, if any.Option (b) is incorrect because the Act does not require the consent of the husband for a Hindu wife to adopt a child.
Option (c) is incorrect because a Hindu wife can adopt a child,
including a boy and a girl.Option (d) is incorrect because the Act does not require the consent of the husband for a Hindu wife to adopt a child.
