Task: Answer the multiple choice question.
Query: Which drug exhibits a 22.000\% 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: O=C1C(=O)c2ccccc2C(O)=C1C1CCC(c2ccc(Cl)cc2)CC1
b: COc1cc(/C=C2\SC(=O)NC2=O)ccc1OCc1ccc(Cl)nc1
c: C1=C(N2CCOCC2)/C(=C/c2nc3ccccc3[nH]2)CC1
d: CCN1CCN(CC(=O)N2c3ccccc3Sc3ccccc32)CC1
e: COCCn1c(SCC(=O)NCc2ccccc2)nnc1-c1ccco1
Answer: d. CCN1CCN(CC(=O)N2c3ccccc3Sc3ccccc32)CC1
