A man who always . . . . . . . . at the faults of his children is their worst enemy.

Solution (By Examveda Team)

Correct Answer: B. connives

Definition of Connive: To connive means to secretly allow or be involved in (something wrong or dishonest); to conspire. It implies a deliberate closing of one's eyes to wrongdoing, often for selfish reasons.

Explanation: The sentence describes a man whose actions negatively impact his children. The word "connives" perfectly fits this context. A man who secretly allows or participates in overlooking his children's faults is, in effect, enabling them to continue making those mistakes and hindering their growth. This makes him their worst enemy, not in a literal sense, but in terms of his detrimental influence.

Why other options are incorrect:
A. appears: To appear at faults suggests merely noticing the faults, which doesn't necessarily imply a negative impact.
C. happy: A man being happy at his children's faults is unusual and doesn't fit the context. The sentence needs a word implying harmful behavior.
D. abstain: To abstain means to refrain from doing something. A man abstaining from pointing out his children's faults might be interpreted as neglecting his role, but it does not necessarily imply that he is their worst enemy. Conniving implies active, harmful participation, whereas abstaining is a passive choice.
