The correct option is B tunnel pressure
When a train enters a tunnel, it compresses the air in front
of it like a piston. Unlike outside air, air in a tunnel can’t be simply pushed
aside—the tunnel walls are in the way. Some of the air is pushed forward, all
the way down to the tunnel’s other end, but most of it rushes through the
narrow space between the train and the tunnel walls, filling in the area behind
the train. Being forced into this narrow space makes the air rush faster,
exactly as water speeds up at the base of a funnel. In fact, this tunnel air
can rush backward much faster than the train’s forward speed. his fast moving
air creates a kind of suction on the train, lowering the air pressure inside
and making your ears go pop. It cause ear aches
Hence, due to sudden
increase and decrease pressure inside tunnel, aches occur in ear
