The key is A, but I am wondering why B is wrong. Would you mind helping me, please?

Hello!
I have seen the following question.
She wants to ________ the police, but she is too young.
A. join
B. go into
The key is A, but I am wondering why B is wrong. Because it is not as good as A. Sometimes multiple-choice questions have more than one at least somewhat acceptable answers. In that circumstance, the best answer is the only correct answer.

People do "go into" the army. But they don't "go into" the police. That is just the way English is.

In BrE, you will hear "go into the police" but not as frequently as "join the police".

Thank Mike and emsr2d2.
By the way, I am wondering which is used with "the armed force", "go into" or "join", please.

 

[emsr2d2]

In BrE, the same applies. Both are used but I hear "join" more frequently. With the armed forces, you also hear "to join up".

I think that it's not a very good question. Sometimes when writing questions, people don't think through all the possibilities- it's easy to do this. It's clear that a) is the answer that they're looking for, but it seems a bit harsh to say that b) is wrong to me.
