Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 19.545% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) COc1ccccc1CNC(=O)CSc1ccc(-c2cccs2)nn1
b) O=C(COC(=O)c1ccccc1SCC(=O)N1CCCC1)NC1CCCCC1
c) CCc1ccc(C(C(=O)NC2CCCC2)N(C(=O)c2csnn2)C2CC2)cc1
d) O=C(COC(=O)CCC(=O)c1cccs1)Nc1ccccc1[N+](=O)[O-]
Answer: d. O=C(COC(=O)CCC(=O)c1cccs1)Nc1ccccc1[N+](=O)[O-]
