In this context, we want to tell that 'it' gives attention to the cognitive process, which in other words means to focus upon it.
Option A is 'focus' which is a noun. Thus, it is wrong. Also, the pronoun is 'it' which is in third person singular form. So, the verb following it should agree with it. So, focus as a verb is also wrong.
Option B is a verb. Also, it agrees with the third person singular form. From the sentence, we can understand that the verb we need refers to pay particular attention to something and it matches with this option.
Option C is wrong because 'it' doesn't jump upon the cognitive processes rather focuses on them.
Option D is a verb which means to give special importance or value to (something) in speaking or writing. It does not match with the given sentence.
Thus, option B is correct.
