Correct answer
A. greatest difference in the sea level at high and low tides
Step-by-step solution
A spring tide refers to the 'springing forth' of the tide during new and full moon, at these times the high tides are higher and the low tides are lower. Spring tides are especially strong tides. This is due to the position of the moon and the sun in relation to the Earth and the resulting gravitational attraction at various stages in the lunar cycle.
