Fill in the blank with the suitable determiner:

It is ______ unaninous decision taken by the team :

a

The correct answer is Option (1) → a

Although "unanimous" begins with a vowel (U), the pronunciation includes a "y" sound before the vowel, so it sounds more like "You-nanimous." The decision to us "a" or "an" is based on the pronunciation.

Thus, in this case we will use 'a'.

"It is a unaninous decision taken by the team."
