Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.489\% 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=c1c2ccc(Cl)cc2nc(-c2cccc(C(F)(F)F)c2)n1O
[b] COC(=O)Nc1nnc(-c2ccncc2)s1
[c] CC(=O)c1ccc(-n2nnnc2SCC(=O)NNC(=O)c2ccco2)cc1
[d] Cc1c(NC(=O)c2ccc3c4c(cccc24)CC3)c(=O)n(-c2ccccc2)n1C
Answer: a. O=c1c2ccc(Cl)cc2nc(-c2cccc(C(F)(F)F)c2)n1O
