Select the most appropriate option to fill in the blank.

A large chunk of lemon crop grown in the country goes ______ to factories.

directly

The most appropriate option to fill in the blank is directly.

The word directly means in a straight line or without any intervening steps. In this case, the sentence is saying that a large chunk of lemon crop grown in the country goes directly to factories. This means that the lemon crop does not go through any other intermediaries before it reaches the factories.

The other options do not make sense in the context of the sentence.

• Director means the person in charge of a film, play, or other production. It cannot be used in this sentence because it does not convey the same meaning of "in a straight line or without any intervening steps".
• Directing means the act of giving instructions or guidance. It cannot be used in this sentence because it is a verb, and the sentence is calling for an adverb.
• Directed is the past tense of the verb direct. It cannot be used in this sentence because it does not convey the same meaning of "in a straight line or without any intervening steps".
