reason of/for a Noun phrase

[spoon]

Hi all,

I have a simple question!

How can I use a preposition after 'a reason'?

for instance:

(a) a reason for the environmental pollution

(B) a reason of the environmental pollution

As far as I'm concerned, I think (a) is probably correct because 'for' usually comes after a noun, reason.

Could you please tell me the correct explanation?

Thanks a million!

of would mean,

EX: the environmental pollution's reason

Hope that helps.

Would you then write
"The reason for the disaster was engine failure, not human error" OR
"The reason of the disaster was engine failure, not human error"?
