Task: Answer the multiple-choice question.
Question: Which drug has a -5.221\% 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 COc1cc([N+](=O)[O-])c(OC)cc1SCc1n[nH]c(=S)n1-c1ccc(C)cc1
b CCCN(C(=O)c1c(CC)noc1C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c COc1ccc(NC(=O)c2sc3nc(C)cc(C)c3c2N)c(OC)c1
Answer: b. CCCN(C(=O)c1c(CC)noc1C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
