The molecular mass of acetic acid $(CH_3COOH)$ dissolved in water is $60$,whereas when dissolved in benzene,it is $120$. This difference in behavior is because:

  • A
    Acetic acid undergoes dissociation in water and association in benzene.
  • B
    Acetic acid undergoes association in water and dissociation in benzene.
  • C
    Acetic acid remains unaffected in both solvents.
  • D
    Acetic acid undergoes dissociation in both solvents.
