To + infinitive v.s. for -ing

Hello everyone. I have a question.

Regarding the following two sentences:

(A) I think this reference book will be useful to write a good report.

(B) I think this reference book will be useful for writing a good report.

I don't quite understand the difference between the two sentences. Are they pretty much the same in meaning? Do they both sound natural? How about these two? --

(C) I think this reference book is useful to write a good report.

(D) I think this reference book is useful for writing a good report.

I don't quite understand the difference between the two sentences. A is wrong grammar in that structure. However, you can use it like this: F or a better understanding of concept, it is useful to write it down in a more formal way.
