Answer:b:3 P.M.

Assumptions:

Distance between two points where Bus meets auto=x

Distance between the point where bus meets auto for the second time and Amritsar=y

velocity of bus=Vb

velocity of auto=va

vb=x/2

va=x/4

y=0.5*vb=05*x/2

time taken by auto for covering the distance y=y/va=1 Hour

hence time at which auto reaches Amritsar=2 P.M.+1 hour=3 P.M.
