I am new to this forum and posting for the first time. Please help me with below Idioms question and also explain the difference with some other examples if possible.

Which sentence is ideomatically correct?
A. She is credited for solving numorous cases.
B. She is credited with solving numorous cases.
C. She is credited as being a great detective.

Thanks all.

Well Credited with and credited for both are correct idiom. It all comes down to in what context you are using.
John should get a lot of credit for the team's success.....Here Credit for is the correct idiom.
Credited with is generally used when some achieved is done......Newton is credited with various laws.

In your sentence A should be right.
