Task: Answer the multiple choice question.
Question: Which drug has a 18.127\% 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 additional words.
Options:
a O=C(NCc1cccc(Cl)c1)c1cccnc1
b CCc1cc2ccc(C)cc2nc1SCC(=O)N1CCN(C(=O)c2ccco2)CC1
c C=C1CCC[C@]2(C)C[C@H]3OC(=O)C(CN4CC(C)OC(C)C4)[C@H]3C[C@@H]12
d N#Cc1c(C(F)(F)F)cc(C2CC2)nc1N1CCCC1
e O=C(CCc1ccc(S(=O)(=O)NC2CCCCC2)cc1)NCc1ccccc1
Answer: d. N#Cc1c(C(F)(F)F)cc(C2CC2)nc1N1CCCC1
