Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.890\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] Cc1ccccc1-n1c(O)c(/C=C2/C(c3ccccc3)=Nc3ccccc32)c(=O)[nH]c1=O
[b] Oc1ccccc1N1CCN(c2ncccn2)CC1
[c] Cn1c2c(c(=O)n(C)c1=O)CN(Cc1ccc(F)cc1)CN2
[d] CC1=C([N+](=O)[O-])C(c2ccccc2)C2=C(N1)c1ccccc1C2=O
[e] CCn1c(SCC(=O)Nc2ccc(NC(C)=O)cc2)nc2c1c(=O)n(C)c(=O)n2C
Answer: c. Cn1c2c(c(=O)n(C)c1=O)CN(Cc1ccc(F)cc1)CN2
