“Since the movie was released seventeen UFOs have been sighted in the state” - is a GMAT sentence correction question. These types of questions contain grammatical errors in the underlined sentence, and we have to choose the correct statement from the options. GMAT sentence correction is part of GMAT verbal.

Answer: B
Explanation:

The guidelines below might be applied to verify the phrase's proposed modification:

• Parallelism
• Considering two distinct facts
• Modifiers

This is how the sentence is put together:

In the state, seventeen UFOs have been observed since the film's premiere, which is more than in the previous ten years put together.

Option A is incorrect:
A is an incorrect response. Since "which" is a relative pronoun, it must be used with a noun. which incorrectly refers to the (near) noun "state" in this statement.

Option B is correct:
the best choice among the given options is B. The part "more than had been sighted.." is a modifier for the noun "seventeen UFOs." Since "which" is a relative pronoun, it must be used with a noun. which incorrectly refers to the (near) noun "state" in this statement.

Choice C is incorrect.
This is an incorrect option. The pronoun "they" wrongly refers to "UFOs."
C has a pronoun 'they' which introduces ambiguity in the sentence and has no clear antecedent.

Choice D is incorrect.
D is an incorrect choice. The comma before the reported, which creates the parallelism problem "having been sighted," must be parallel to what comes following more than.

Choice E is incorrect.
This is the incorrect choice. This sentence uses “had” just after the use of the word "than." It is inappropriate and does not make any sense when put in the given statement. This cannot be the correct answer.
