It changes the meaning of the original sentence but I believe it is grammatically correct.

who does refer to Curt Gowdy as 'who' cant refer to the organization..

Sachindia, you've answered your own question! You're right, B is grammatically correct. So is C! Once you're eliminated the grammatically incorrect answer choices (D and E, because they use unnecessarily complex verb tenses), you must then look to the meaning. Any of these 3 - A, B, or C - could be correct depending on the context. If that's the case, you must default to the original meaning of the sentence, which would be A.

In B, both "a spokesman" and the "who" clause are modifying Curt - he was the spokesman, and he was 86. Noun modifiers modify the noun that preceded them.

In C, though, the "who" clause is just modifying the spokesman - that's the noun preceding it. The spokesman is 86, and he said that Curt died. So Curt is not the one being modified, and he's not the spokesman - the spokesman said something about him, so it's clear that they're two different people. The answer explanation given is actually correct.

Does that help?
