Task: Answer the multiple choice question.
Query: Which drug has a -8.565% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a CC(=O)c1ccc(OCC(=O)N2CCCC(N3CCN(c4ccccc4C)CC3)C2)cc1
b COC(=O)c1cc2c(ccc3ccccc32)oc1=O
c OC(CNCc1ccccc1)COc1ccccc1
d C(=C/CSc1ncn[nH]1)\CSc1ncn[nH]1
e COc1ccccc1NS(=O)(=O)c1ccc(C(=O)NCC2(N(C)C)CCCCC2)cc1
Answer: b. COC(=O)c1cc2c(ccc3ccccc32)oc1=O
