    I think acidic nature completely depends on the stability of the conjugate base. For OR the R group will pump electrons on the O which makes it less stable than OH.

    option B is correct

    CH3OH is more acidic than water. So CH3O- is more stable than OH-

    option B. Nucleophilicity increase, rate of NSR increase

    why oh is more nucleophilic than OR

    eduncle-logo-app

    When negative charge is present on same type of atom in different nucleophiles, the order of nucleophilicity is determined by taking the strength of their conjugate acids. If the acid is strong its nucleophilicity is less. CH3OH is a slightly more acidic (pKa=15.5) than H2O (pka=15.74). Therefore hydroxide ion is slightly more nucleophilicity than methoxide ion
