Answer: The correct option is (B)
(2b+3)(2b-3).

Step-by-step explanation: We are given to factorize the following expression :


E=4b^2-9.

We will be using the following factorization formula :


a^2-b^2=(a+b)(a-b).

The factorization is as follows :


E\\\\=4b^2-9\\\\=(2b)^2-3^2\\\\=(2b+3)(2b-3).

Thus, the required factored form is
(2b+3)(2b-3).

Option (B) is CORRECT.
