Find out the correct option for the given sentence.

Concept

A standard English declarative sentence follows the order Subject -> Verb -> Complement. The subject (the doer) comes first, then the verb, then any complement or object. The adjective negligent is predicative here and takes the preposition of, giving the fixed pattern "negligent of (something)".

Application

Identify the parts and place them in normal order:

• Subject: Mohan

• Verb: was

• Complement: negligent of his duties

Arranged as Subject + Verb + Complement, the natural sentence is: "Mohan was negligent of his duties." Nothing is inverted, fronted, or turned into a question, so this reads as a plain, grammatical statement.

Contrast

• "Of his duties negligent, was Mohan" — the complement is fronted and the subject pushed to the end; this poetic/archaic inversion is not standard prose order.

• "Negligent was Mohan of his duties" — the adjective is fronted before the subject and the "of his duties" phrase is split off, breaking normal word order.

• "Was Mohan, of his duties, negligent" — placing the verb "Was" first turns it into an interrogative shape, not the required declarative statement.
