To factor by grouping, we need to find a common factor between the first two terms and the last two terms. Both terms have "ec" and "ab" as common factors. Factoring out "ecab" from the first two terms gives $ecab(11e+8d)$, and factoring out "ab" from the last two terms gives $ab(6684e+3be5)$. So the expression becomes $ecab(11e+8d)+ab(6684e+3be5)$, which matches choice C.
