Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.346\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a S=c1[nH]nc(COc2ccccc2)n1/N=C/c1ccc(Cl)cc1
b CCOC(=O)N1CCN(C(=O)C2CC(=O)N(c3ccc(OC)cc3)C2c2ccc(OC)cc2)CC1
Answer: a. S=c1[nH]nc(COc2ccccc2)n1/N=C/c1ccc(Cl)cc1
