Study the following statements. i) Levees are constructed parallel to river flow, ii) Spurs are constructed parallel to river flow, iii) Levees are constructed transverse to river flow, iv) Spurs are constructed transverse to river flow. The correct answer is A. (i) and (ii) B. (i) and (iv) C. (ii) and (iii) D. (iii) and (iv)

The correct answer is A. (i) and (ii).

Levees are constructed parallel to river flow to protect areas from flooding. They are typically made of earth or rock and are designed to withstand the force of the river’s current. Spurs are constructed perpendicular to river flow to help control erosion. They are typically made of concrete or steel and are designed to deflect the river’s current away from the riverbank.

Here

The levee is the long, straight structure that runs parallel to the river. The spur is the shorter, V-shaped structure that runs perpendicular to the river.

I hope this explanation is helpful!
