Options

  1. AOne phenyl group is replaced by a methyl group.
  2. BOne phenyl group is replaced by a para-methoxyphenyl group.
  3. CTwo phenyl groups are replaced by two para-methoxyphenyl groups.
  4. DNo structural change is made to X.

Correct answer

C. Two phenyl groups are replaced by two para-methoxyphenyl groups.
