Task: Answer the multiple choice question.
Query: Which drug exhibits a 19.626% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:

[b] Cc1ccc(CNC(=O)CN(C(=O)C2(C)CC(=O)N=C3C=CC=CN32)c2ccc(F)cc2)cc1
[c] CNc1ccc(Br)cc(C(=O)/C=C/c2cccc(OC)c2OC)c1=O
[d] Cc1ccc(C)c(N2CCN(C(=O)c3ccc(N4CCOCC4)c([N+](=O)[O-])c3)CC2)c1
Answer: b. Cc1ccc(CNC(=O)CN(C(=O)C2(C)CC(=O)N=C3C=CC=CN32)c2ccc(F)cc2)cc1
