Task: Answer the multiple choice question.
Query: Which drug has a 4.724\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=c1c2ccccc2[nH]c(=S)n1CCC1=CCCCC1
b: COc1ccc(N=c2oc3cc(O)ccc3cc2C(=O)NCC2CCCO2)c(OC)c1
c: Cc1nc(-c2ccccc2)[nH]c(=O)c1Oc1ccc(Cl)cc1Cl
Answer: b. COc1ccc(N=c2oc3cc(O)ccc3cc2C(=O)NCC2CCCO2)c(OC)c1
