Fully constructive interference between two sinusoidal waves occurs only if
they are in phase
and they are travelling in same direction
if they are travelling in differnet direction (ooposite directions)
then
for constructive interference, they need to be in phase with their maximas aligned as well
hence
option c is the answer
