Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.418\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=c1[nH]c(=O)n(Cc2ccco2)c(O)c1C=NC1CCN(Cc2ccccc2)CC1
b CN(C)S(=O)(=O)c1cccc(NC(=O)c2cccc(NS(=O)(=O)c3ccccc3)c2)c1
c Cc1cccc(C)c1NC(=O)CCc1nnc2ccc(N3CCCC3)nn12
d O=C(c1cc2cc(Cl)ccc2[nH]1)N1CCN(c2ccccn2)CC1
e CCCn1nnnc1NCc1ccc(OC)cc1OC
Answer: d. O=C(c1cc2cc(Cl)ccc2[nH]1)N1CCN(c2ccccn2)CC1
