Answer should be B
Consider the $1^{\text{st}}$ production $S \to abScT$
This production generates equal number of $(ab)$'s and $c$'s but after each $c$ there is $T$ which goes to $T \to bT$
So, with each $c$ there can be one or more $b$'s (one because of production $T \to b$ and more because of $T \to bT$)
and these $b$'s are independent.
For example,
$ababcbbcbb$ is the part of the language
and $ababcbbbbbbcbb$ is also the part of the language so we can rule out options A and C as both say equal number of $b$'s after each $c.$
In option D equal number of $(ab)$'s and $c$'s is not satisfied. The only option that satisfies these $2$ conditions is option B.
