When we look at artists' self-portraits we get a glimpse of their feelings during that particular time period. What is the correct way to write this sentence

This question is missing the options. I've found the complete question online. The options are the following:

A. When we look at artists' self-portraits, we get a glimpse of their feelings during that particular time period.

B. When we look at artists' self-portraits, we get a glimpse of their feelings, during that particular time period.

C When we look at artists' self-portraits we get a glimpse, of their feelings during that particular time period.

D. When we look at artists', self-portraits we get a glimpse of their feelings during that particular time period.

The option that has the correct way to write the sentence is:

A. When we look at artists' self-portraits, we get a glimpse of their feelings during that particular time period.

Explanation:

The sentence we are analyzing here can be divided into two clauses:

1. When we look at artists' self-portraits,

2. we get a glimpse of their feelings during that particular time period.

If we had begun with clause 2, which is an independent clause, there would be no need to use a comma between the two clauses. However, clause 1 is a subordinate clause and, because we started with it, a comma is necessary. However, that is the only comma we need in the whole sentence. Placing a comma anywhere else would change the sentence's meaning or simply make it incorrect, separating elements that should not be separated, such as subject and predicate, for instance.
