Task: Answer the multiple choice question.
Query: Which compound exhibits a -4.582% 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=C1NC(=Nc2cccnc2)S/C1=C/c1ccc(F)cc1
b. COCCNC(=O)CSc1nc(-c2ccc(OC)c(OC)c2)cc(C(F)(F)F)n1
Answer: a. O=C1NC(=Nc2cccnc2)S/C1=C/c1ccc(F)cc1
