Task: Answer the multiple choice question.
Question: Which drug has a 6.708\% human ether-à-go-go related gene (hERG) inhibition at 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(O)c1cccc2[nH]c(C(F)(F)F)nc12
(b) COc1ccc(C)cc1NC(=S)NNC(=O)c1ccccc1Cl
(c) Cc1ccc(C(=O)N/C(=C/c2ccco2)C(=O)NCC2CCCO2)cc1
(d) COc1ccc(Cn2c(=S)[nH]c3ccsc3c2=O)cc1
Answer: a. O=C(O)c1cccc2[nH]c(C(F)(F)F)nc12
