Task: Answer the multiple-choice question.
Question: Which drug has a 19.850% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. Cc1c[nH]c(=O)c([N+](=O)[O-])c1
b. CC(Cc1ccccc1Sc1ccccc1)N(C)C.O=C(O)/C=C\C(=O)O
c. COc1ccc2oc(=O)c(C(=O)N3CCN(c4ccccc4F)CC3)cc2c1
d. CC(C)CC1Nc2ccc(C(=O)NCCCN3CCCCC3C)cc2NC1=O
e. Cn1c(=O)c(C(=O)NNC(=O)c2ccccc2F)c(O)c2ccccc21
Answer: a. Cc1c[nH]c(=O)c([N+](=O)[O-])c1
