Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 11.323\% 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. Cn1c(=O)c2c(nc3n2CC(O)CN3c2ccc(O)cc2)n(C)c1=O
b. COc1ccc(-c2nn(C)c(=O)[nH]2)cc1
c. O=C(COC(=O)CC1CCCC1)Nc1ccccc1[N+](=O)[O-]
d. COCCCN(C(=O)CSCC(=O)Nc1cccc(C)c1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: c. O=C(COC(=O)CC1CCCC1)Nc1ccccc1[N+](=O)[O-]
