Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.874% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) O=S(=O)(c1c(Cl)sc(Cl)c1Br)N1CCCC1
b) CCOC(=O)C(CC)Sc1ncnc2c1nnn2-c1ccc(F)cc1
Answer: a. O=S(=O)(c1c(Cl)sc(Cl)c1Br)N1CCCC1
