Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.872% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a COCCNC(=O)c1cc2c(=O)n3cccc(C)c3nc2n(Cc2ccncc2)c1=N
b O=C(CCC(=O)N/N=C/c1ccco1)N/N=C/c1ccco1
Answer: b. O=C(CCC(=O)N/N=C/c1ccco1)N/N=C/c1ccco1
