(a) To live, to love
(b) to serve, and
(c) also admiration are what
(d) I aspire for

The phrase "also admiration are what" is grammatically incorrect .Therefore, Option C is the correct answer.

The sentence states "To live, to love, to serve"—all are infinitive phrases (verb forms). However, "also admiration" is a noun phrase, which does not match the pattern of the other items in the list.

The correct version would be: "To live, to love, to serve, and also to admire are what I aspire for."
