Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.192\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) COc1ccc(N(C(=O)c2ccc(Br)o2)C2C=CS(=O)(=O)C2)c(OC)c1
b) C=CCc1ccc2oc(C(=O)OCC)cc(=O)c2c1O
c) COc1ccc(N2CCN(S(=O)(=O)c3ccc(-n4cnnn4)c(C)c3)CC2)cc1
d) Cc1cccc(NC(=O)CCc2nc3sc4c(c3c(=O)[nH]2)CCCC4)n1
e) CCC(NS(=O)(=O)c1ccc(C)cc1)C(=O)N1CCC2(O)CCCCC2C1
Answer: b. C=CCc1ccc2oc(C(=O)OCC)cc(=O)c2c1O
