Which of the following stilling basin help in stabilizing the flow and improve the jump performance?

(a) dentated sills

(b) chute blocks

(c) baffle piers

(d) friction blocks

I got this question in an interview for job.

I want to ask this question from Energy Dissipation Below Overflow Spillway in chapter Spillways, Energy Dissipators and Spillway Gates of Irrigation Engineering

Right answer is (b) chute blocks

Best explanation: Chute blocks are a row of small projections like teeth of saw and are provided at the entrance of the silting basin. It produces a shorter length of jump and stabilizes the flow. Hence, they improve jump performance.
