Task: Answer the multiple choice question.
Query: Which drug has a 10.509% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=C1NC(=O)/C(=C/c2ccco2)N1
b) Cc1sc(-c2ccncc2)nc1OC(=O)c1ccccc1
c) COc1ccc(-c2noc(CSc3ccc(C)cc3)n2)cc1
Answer: a. O=C1NC(=O)/C(=C/c2ccco2)N1
