Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 16.210\% 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. CN1CCCC(OC(=O)C(c2ccccc2)c2ccccc2)C1
b. O=C(O)C1C2C=CC(C2)C1C(=O)Nc1nccs1
c. N#Cc1c(NC(=O)c2cccc(S(=O)(=O)Nc3ccc(C(=O)O)cc3)c2)sc2c1CCCC2
d. Cc1ccn2c(NC(=O)c3ccccc3)c(-c3cccs3)nc2c1
Answer: b. O=C(O)C1C2C=CC(C2)C1C(=O)Nc1nccs1
