Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -3.409\% 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(Nc1cc2c(ccc3ccccc32)oc1=O)C1CCCCC1
b O=c1[nH]cnc2c1c(-c1ccccc1)cn2-c1ccc(Br)cc1
c Cc1nn(CCC(N)=S)c2nc(-c3cccs3)cc(C(F)(F)F)c12
d COc1ccc(S(=O)(=O)N(C(=O)c2ccncc2)c2ccc3oc4c(c3c2)CCCC4)cc1
Answer: a. O=C(Nc1cc2c(ccc3ccccc32)oc1=O)C1CCCCC1
