Solution

The correct options are
C $T_{1}, T_{2}, T_{3},$ and $T_{4}$ are all opened
D $T_{1}$ is opened and the content bucket is poured in the tub
In the following cases, the will solution in tub have a pH different from other.
(C) $T_{1}, T_{2}, T_{3}$ and $T_{4}$ are all opened. The resulting solution in tub will be acidic with pH less than $7$ . The solution in bucket is neutral with pH $7$ .
(D) $T_{1}$ is opened and the content bucket is poured in the tub. The resulting solution in tub will be acidic with pH less than $7$ . In other solutions, one is $N a O H$ solution which is basic with $p H > 7$ .
