Task: Answer the multiple choice question.
Query: Which compound exhibits a 10.665\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COC(=O)c1ccc(COc2ccc3c4c(c(=O)oc3c2)CCC4)o1
b: O=C(NC(CO)(CO)CO)c1coc(=O)c(Br)c1
c: NS(=O)(=O)c1ccc(Sc2nc3ccccc3s2)c([N+](=O)[O-])c1
Answer: b. O=C(NC(CO)(CO)CO)c1coc(=O)c(Br)c1
