Task: Answer the MCQ question.
Query: Which drug exhibits a 21.192\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] Cc1ccc(-n2c(SC3CCOC3=O)nc3ccccc3c2=O)cc1
[b] CCCCCCc1cc2cc(C(=O)OCC)c(=O)oc2cc1O
[c] Cc1cc(C)cc(N=Cc2c(O)c3ccccc3oc2=O)c1
[d] C[C@@H](CO)NC(=O)c1ccc2c3n(nc2c1)-c1ccc(Cl)cc1CO3
