Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.362\% 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 additional words.
Options:
(a) NC(=O)C[n+]1ccc(/C=N/O)cc1.[Cl-]
(b) O=c1[nH]c(C2CCCN(S(=O)(=O)c3ccccc3)C2)nc2c1nnn2Cc1ccccc1
(c) COc1ccccc1N1CCN(C(=O)C(C)N(c2ccc(C)cc2)S(C)(=O)=O)CC1
(d) N#Cc1cccc(NC(=O)CNC(=O)Cc2ccccc2)c1
Answer: c. COc1ccccc1N1CCN(C(=O)C(C)N(c2ccc(C)cc2)S(C)(=O)=O)CC1
