I think D) ADSPEC can be enabled on individual LSPs is the false statement. It doesn't make sense to me.

But I remember reading that ADSPEC sets an SDP's MTU to the smallest MTU value found along the LSP path, so I think it's A).

D is definitely false. ADSPEC is a global setting, not something you can enable on individual LSPs.
