an extensive history

[keannu]

Why is b the only answer? I think c can be, too. When you use "a" it's one of many, unspecific, so if there's many other kinds of documentaries except this, it's possible, but if there's only of this documentary, then this should be "the". I don't understand why b is the only answer, the tester may have made a mistake.

Q. The TV studio on the third floor is renowned for ___b____ of producing award-winning documentaries.
a)extensive history
b)an extensive history
c)the extensive history
d)any extensive history

It's the history that's extensive, not the documentaries.

However, I don't like any of those choices. I'd say "its" instead of "an."
