Task: Answer the multiple choice question.
Question: Which drug has a -18.078\% 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 Cc1ccc(Cn2nc(C)c(NC(=O)CSc3nc4c(c(C(F)(F)F)n3)CCc3ccccc3-4)c2C)cc1
b N#Cc1ccc(COC(=O)c2cccnc2Cl)cc1
c Cc1cccc(NC(=O)C2CCCN2C(=O)OCC(C)C)c1C
d O=C1CC(c2ccc(F)cc2)C2=C(CCCC2=O)N1
e O=C1CCc2cc(S(=O)(=O)N3CCC(C(=O)NC4CCCCCCC4)CC3)ccc2N1
Answer: b. N#Cc1ccc(COC(=O)c2cccnc2Cl)cc1
