Task: Answer the multiple choice question.
Question: Which drug exhibits a -21.457% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. Cl.O=C(CSc1ncc(-c2ccc(F)cc2)[nH]1)N1CCCCC1
b. CN(C)CCNC(C(=O)Nc1cccc(S(=O)(=O)N2CCOCC2)c1)c1ccccc1
Answer: a. Cl.O=C(CSc1ncc(-c2ccc(F)cc2)[nH]1)N1CCCCC1
