Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 10.488\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. COc1ccc(-c2nn(CCC#N)cc2C(=O)Nc2ccccc2Cl)cc1
b. Cc1sc2nc(CSc3ccc([N+](=O)[O-])cc3)[nH]c(=O)c2c1C
c. CC(=O)c1cc2c(cc1NC(=O)CN1CCCCC1C)OCO2.O=C(O)C(=O)O
d. COc1cc2c(cc1OC)CN(C(=O)CSc1n[nH]c(N)n1)CC2
Answer: b. Cc1sc2nc(CSc3ccc([N+](=O)[O-])cc3)[nH]c(=O)c2c1C
