a) Is he?

d) Has he?

Answer 1

Hint: To ask a question in English you must usually use one of the auxiliary verbs (be, do, have) or a modal verb such as can, will, may. If you are expecting a yes/no answer, then the question starts with the auxiliary or modal.

Complete answer:
A question tag is a grammatical structure in which a declarative or an imperative statement is turned into a question by the addition of an interrogative fragment. For example: “You’re John, aren’t you?”, the statement “You’re John” is turned into a question by the tag “aren’t you”. In the given question, we have to complete the phrase by adding a question tag.
Now, let us examine all the given options to find out the correct answer :
Option ‘a’ is Is he? It cannot be the correct answer as there is a rule about question tags, we cannot use a negative question tag after a negative statement, and a positive question tag after a positive statement. The given statement is positive, so the question tag must be negative.
Option ‘b’ is Hasn’t he? It cannot be the correct answer as well because the statement is focusing on the word ‘is’ and not ‘has’.
Option ‘c’ is, isn’t he? It is the correct answer as it is a negative tag, followed by a positive statement. It also has ‘is’ in it. The statement focuses on it, so it is the correct option.
Option ‘d’ is Has he? It is again an incorrect option as it is a positive question tag and cannot be used in the given blank. Hence, option ‘c’ is the correct option.

Note:
The tense of the tag is determined by the tense of the auxiliary/modal verb of the statement that precedes it. If the statement does not use an auxiliary/modal (i.e. it is in the present or past simple tense), then the auxiliary to do must be used.
