Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.123\% 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 additional words.
Options:
a. O=C(Cn1c(Cc2ccccc2)nc2ccccc21)NCc1ccc2c(c1)OCO2
b. CCc1nc(SCC(=O)Nc2cc(C)on2)n[nH]1
c. Cc1ccc(CS(=O)Cc2ccc(C(=O)N3CCN(c4ccccc4)CC3)o2)cc1
d. COc1cccc(CN2CCN(Cc3ccco3)CC2)c1.O=C(O)C(=O)O
Answer: a. O=C(Cn1c(Cc2ccccc2)nc2ccccc21)NCc1ccc2c(c1)OCO2
