Task: Answer the multiple-choice question.
Question: Which drug has a -1.371\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccc(C2c3ccc(O)cc3Oc3ncn4nc(-c5ccccn5)nc4c32)cc1OC
b CN(C)CCCNC(=O)c1ccc(Cl)c(S(=O)(=O)N2CCCCCC2)c1.Cl
c CC(C)(CO)NS(=O)(=O)c1ccc2c(c1)Cc1cc(S(=O)(=O)NC(C)(C)CO)ccc1-2
d CCCC(C(=O)O)N1C(=O)/C(=C2\C(=O)N(C)c3ccccc32)SC1=S
Answer: d. CCCC(C(=O)O)N1C(=O)/C(=C2\C(=O)N(C)c3ccccc32)SC1=S
