Task: Answer the multiple-choice question.
Query: Which drug has a 4.376\% 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: COc1cccc(OCC(O)CN(CCO)Cc2ccccc2)c1.Cl
b: O=C(Nc1nc2ccsc2c(=O)s1)c1ccco1
c: CC1(C)CC(=O)C=C(NCC2CCCO2)C1
d: N#Cc1c(-c2ccccc2)ccn(Cc2cccc(Cl)c2)c1=O
Answer: a. COc1cccc(OCC(O)CN(CCO)Cc2ccccc2)c1.Cl
