Could someone answer this question, i'd appreciate it. Im stuck on it

The C-O-H bond angle is wider in methanol compared to water, and the C-O bond is longer then the OH bond in water due to:

A) Steric clashing of methyl C-H's and hydroxyl H.
B) Unshared pairs in water scissor H's inward, an effect not seen in methanol.
C) Water is constantly exchanging H's while methanol is not.
D) All of these
E) None of these
