Task: Answer the multiple-choice question.
Question: Which drug has a -5.977\% 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(CCc1nc2ccccc2[nH]1)N1CCN(C(=O)c2ccco2)CC1
b: CN(C)c1cccc(C(=O)NCC2CCCO2)c1
c: O=C(Nc1cccnc1)Nc1ccc2c(c1)OCO2
d: CCOc1ccccc1C(=O)N1CCCCC1C
Answer: c. O=C(Nc1cccnc1)Nc1ccc2c(c1)OCO2
