When edward snowden let the cat out of the bag, he ruined our country's intelligence system" is a poorly phrased central idea for an informative speech because it?

It  is a poorly phrased central idea for an informative speech because it: contains figurative language

There is no actual explanable explanation why a cat out of the bag could influence our country's intelligence system.
This phrase need a little bit more explanation about the correlation to be considered as 'informative'

Ithink it would be choices a and b. hope this !
