Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.180\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CCC1Oc2ccccc2N(CC(=O)Nc2ccc(OC)cc2OC)C1=O
b COc1ccc(OC)c(C(=O)c2ccc(C(=O)c3cc(OC)ccc3OC)cc2)c1
c CC(C)c1cc(C(=O)N/N=C/c2cccnc2)n[nH]1
Answer: a. CCC1Oc2ccccc2N(CC(=O)Nc2ccc(OC)cc2OC)C1=O
