Task: Answer the multiple choice question.
Query: Which drug has a 12.580\% 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 O=C(COC(=O)CNC(=O)c1ccc(Br)o1)Nc1ccccc1OC(F)F
b CO/N=C(/CS(=O)c1ccc(Br)cc1)c1ccc(OC)cc1
c CCOc1ccccc1-n1c([S-])c(C(=O)Nc2ccc(C)cc2)[n+]2ccccc12
d N#C/C(=C\c1ccccc1)C(=O)NC1CC1
Answer: d. N#C/C(=C\c1ccccc1)C(=O)NC1CC1
