E is better.
Logic- As comparison is based on mechanism so "that of" is required at end...so left with c and e ...e is more clearly..

A, B and C imparts illogical meaning,
Maesanin,modifier, has an antibacterial action.... - Maesanin can not has an action of its own, it can perform the action...thats what d and e states

A noun cannot posses any "action" by its own, it can only perform the action.

Hope this helps !!!
