Hello.

I'm really confused about the usage of "by" and "with". Where should I use these prepositions? For instance, which of the following sentences is grammatical?

A) Terrorists attacked London by car bombs.

B) Terrorists attacked London with car bombs.

Thank you in advance.

Use the second one (B). Terrorists attacked London with car bombs. In other words, they used car bombs to attack London.
