Regarding the option - Given a CFG. Is it empty or not?

Since the Language is (<G>| G is a CFG and L(G) is empty). We can find one TM which accepts an empty string and one which doesn't. Then by Rice's theorem, this property is non trivial and thus undecidable for Recursively Enumerable languages which involve CFLs.

What am I missing here?
