Answer 2

• He had built a unique house.

• (a) An (b) A (c) The.

　

Justification :

• An: This gives an vowel sound so we don't use an infront of the word "unique".

　

• A: This is the right world, "A unique house" - Refers to "A single good house".

　

• The: Generally we dom say "The house", We don't use the word "The" infront of the word house because it doesn't make a perfect sentence.

　

Example :

We say:

1. "He built a house".
2. "They built a house".

　

Because,

• This is the perfect word which helps the sentence to be unique.
