The midge ..... to any of several species

[Freeguy]

The midge ..... to any of several species of small flies, refers to a mosquito-like insect slender wings and body, long legs, and antennae.

1. which a term applied
2. a term applied
3. is a term applied
4. applied a term

According to relative clauses, I'd pick up No.4. However, I have doubt about the accuracy of No.2. Would you please tell me which of them is the best one and is it correct to say: The midge a term applied to .... ( following two noun together I mean)

Thanks

Have you missed a comma after 'midge'?

If the book missed it out, no grammatical answer is possible.

One of the reasons that made me confused is what you precisely said. No. There is no comma after midge. It's PBT test. The answer key picked up No.2 as a correct answer. But using The midge and a term together without any pause between sounds awkward to me.

This would work: The midge, a term applied to any of several species of small flies, refers to a mosquito-like insect slender wings and body, long legs, and antennae.
As discussed, you need a comma so "a term applied to any of several species of small flies" is a non-restrictive clause.

This would work: The midge is a term applied to any of several species of small flies, and refers to a mosquito-like insect slender wings and body, long legs, and antennae.
You need a conjuction to avoid a comma splice.

#4 would not work.
