Question

Fill in the blank with a suitable option:
I can’t imagine _____________
A) Why did he recommend him
B) Who recommended him for training
C) When will he recommend me
D) How will he recommend him

Answer 1

Hint: The above sentence indicates that it is an example of a noun clause. A noun class should consist of both verb and subject but does not possess a meaning when it exists individually.

Complete answer:
A noun class usually starts with words such as who, when, or where, and certain conjunctions like “that”, followed by a noun, the noun indicated here is a person represented as “he”. Thus the option “who recommended him for training” seems the most appropriate.
Considering the other given options one by one-
“Why did he recommend him” cannot be an appropriate usage since here the verb is followed by the noun in the noun clause, also the usage doesn’t form a meaningful proper sentence.
“When will he recommend me” is also an inappropriate usage since the sentence also fails to develop in a meaningful manner.
“How will he recommend him” also is inappropriate due to failure to construct a meaningful sentence.
Thus from the above-given options, the most appropriate one was found to be B, since it forms a noun clause and thereby a meaningful sentence. Therefore the properly constructed sentence is: “I can’t imagine who recommended him for training.”

Note:
A noun clause can have a variety of functions corresponding to a subject, object, or a compliment. The various noun clauses are the subject of a verb, an object of a verb, subject complement, object of a preposition, or adjective complement. These clauses have an inability to stand alone. Unlike adjectives, they are no modifiers. They are dependent clauses and functions as a noun.
