Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.624\% 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. CCCc1noc2c1/C(=N\O)CC(CC(C)SCC)C2
b. CNc1nc(N)c([N+](=O)[O-])c(NCCO)n1
c. C=CCN(CC=C)S(=O)(=O)c1ncn[nH]1
Answer: b. CNc1nc(N)c([N+](=O)[O-])c(NCCO)n1
