I also think the answer lies in the meaning of complex model silicon. Else what @Savan said is right.

In forward bias potential barrier decreases and therefore current increases ---> this simply implies that with the increase in current, potential barrier decreases.

In forward biasing, when 'p' terminal is connected with 'p' side of the battery and 'n' terminal is connected with 'n' side of the battery, then the potential barrier is increasing with increase in voltage because holes are attracted by positive charge and electrons is attracted by the negative charge.

It should be D. Agree @Dharma Mohan.
