Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -8.821\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CC1(C)Nc2ccccc2N(Cc2ccc([N+](=O)[O-])cc2)C1=O
[b] COc1c(C(=O)NC(=S)Nc2nnn(C)n2)cc2ccccc2c1Br
[c] CCOC(=O)C1(CCOc2ccccc2)CCN(Cc2cnc(SC)nc2)CC1
[d] Cc1cc(C)nc(/N=C(\N)Nc2ccc(OCCC(C)C)cc2)n1
Answer: b. COc1c(C(=O)NC(=S)Nc2nnn(C)n2)cc2ccccc2c1Br
