What happens if you brake too hard in a smooth bore tanker?

a.The baffles absorb the impact
b.The liquid surges forward with great force, pushing the truck and possibly causing a skid or jackknife
c.The tank automatically releases pressure
d.Nothing different from a regular truck

Explanation

Braking too hard in a smooth bore tanker causes the liquid to surge forward with great force because there are no baffles to slow it down. This forward surge pushes the truck, making it very difficult to stop and potentially causing a skid or jackknife.
