B. pour the reagent into a small beaker before using it

Explanation:

Let's explore all the mentioned practice

A. Leftover reagents should not be discarded in the sink but discarded according to the disposal method present in the safety data sheet (SDS) of the chemical.

B. Reagents should be poured in a clean beaker for use to avoid contamination in the original reagent bottle

C. This is not a good practice, as the plastic pipet tends to contain some impurity in its tip.

D. This is also a bad practice. Firstly, a reagent should be taken according to the need. If there is leftover, it should be discarded as it most probably contains contamination in it
