[Grammar] have ... broken

[Hồ Quang Trung]

This is the third time that the lenses of my glasses have ... broken.

A. all
B. both
C. each
D. any

I think the lenses don't refer to 2.

B is okay if the number of the lenses is only 2.

A is okay, I am not sure why ALL is not correct.

If you fight here, you will all die.

C is the answer. I searched have each broken and found a number of examples. However, which function/ part of speech each has in this phrase? I see each could be a pronoun/ a determiner.

I think the sentence would be better with nothing in the blank.

It's a good idea. However, this question is a TOEIC one. I have no choice but have to choose a letter.

If I had to choose, I would choose B.

How many lenses are typically in glasses in Vietnam? We use two here, one for each eye.

Glasses in English refers to a pair of glasses or the number can be more than one pair? What happens if I want to use two pairs of glasses and just say, lenses of glasses?

If I say "I've broken my glasses", we don't know if I've broken one lens, both lenses, the arms, the nosepiece or something else. If I have broken one lens, I would say "I've broken one of the lenses in my glasses". If I was unfortunate enough to break both, I would say "I've broken both the lenses in my glasses!"

Without further context, I would assume that the person had broken the lenses in one pair of glasses. If they had broken more than one pair, they would almost certainly say so, so B is the best answer there.
