Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.517\% 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, or c without using any additional words.
Options:
a OCCN1CCOCCN(CCO)CCN(CCO)CC1
b CCOc1cc2c(cc1OC)C(NC(=O)C(F)(F)F)CC2=O
c CSc1ccccc1-c1nnc(-c2ccc(Cl)cc2)o1
Answer: b. CCOc1cc2c(cc1OC)C(NC(=O)C(F)(F)F)CC2=O
