In the first question, the answer is - D. A - cannot be the correct answer as common nouns (such as - chair, computer, desk) don't have to be written in capital letters. And regarding B, proper nouns (such as John, Thames. America) always have to begin with a capital letter. C - is simply incorrect, using proper nouns, that is, names, isn't more polite than saying, for example, a wall.

Regarding the second question, the answer is - B. It is the only sentence in which the past simple tense of the verb "to bring" is used. The first example uses the present perfect tense (which isn't a past tense), C - present continuous, and D - future simple.
