He was .......in the deception by his wife.
B
Correct answer
Explanation
The sentence requires a past participle to complete the passive construction 'was [verb] in the deception'. 'Abet' means to encourage or assist, usually in wrongdoing. 'Abetted' is the past tense and past participle of abet. 'Abed' means in bed. 'Abduct' means to kidnap. 'Was abetted in the deception' means he was assisted or encouraged in the wrongdoing.
