Task: Answer the multiple-choice question.
Question: Which compound has a 2.473\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C1CC(c2nc3ccccc3[nH]2)CN1c1cccc(C(F)(F)F)c1
b CC(C)OCCCNC(=O)c1c(N)n(CC2CCCO2)c2nc3ccccc3nc12
c CCO.Cn1c2c(c(=O)n(C)c1=O)[C@@]1(C(=O)Nc3ccccc31)C(C#N)=C(N)O2
d COc1cc(NC(=O)C(c2ccccc2)c2ccccc2)c(C(=O)O)cc1OC
Answer: a. O=C1CC(c2nc3ccccc3[nH]2)CN1c1cccc(C(F)(F)F)c1
