Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.833\% 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 or b without using any additional words.
Options:
(a) O=C(Nc1ccc(F)cc1Cl)c1ccc2c(=O)n3c(nc2c1)CCC3
(b) COc1ccc(CCNC(=O)c2ccc3c(c2)N(Cc2ccc(C)cc2)CCS3)cc1OC
Answer: a. O=C(Nc1ccc(F)cc1Cl)c1ccc2c(=O)n3c(nc2c1)CCC3
