Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 17.810\% human ether-à-go-go related gene (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.) O=C(Nc1ccc(C(F)(F)F)cc1)c1ccccc1Br
b.) CCC(CC(C)(C)O)C(=O)NNC(=S)Nc1ccccc1
c.) CC(C)c1ccc(N2C(=O)CC(=O)NC2=O)cc1
d.) COc1ccc(OC)c2nc3c(cc12)CCC3
e.) O=C(O)c1ccccc1-c1ccccc1C(=O)Nc1cccc(O)c1
Answer: d. COc1ccc(OC)c2nc3c(cc12)CCC3
