Task: Answer the multiple-choice question.
Query: Which drug has a -15.453\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCOP(=O)(c1ccccc1)C(O)c1ccc(Br)cc1
b CCN(CC)CC(O)CN(c1ccccc1)S(=O)(=O)c1ccc2ccccc2c1.Cl
c Cc1nc(SCC(=O)c2ccc(F)c(F)c2)[nH]c(=O)c1Oc1ccc(F)cc1
d CC(C)N(Cc1nccn1C)C(=O)c1cc(COc2ccc(F)cc2Cl)on1
e O=C(c1ccc(CS(=O)c2cccc(Cl)c2)o1)N1CCCCCC1
Answer: a. CCOP(=O)(c1ccccc1)C(O)c1ccc(Br)cc1
