Problem statement: Answer the multiple choice question.
Query: Which drug has a 14.263\% 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, or c without using any other words.
Options:
a. O=C1CCN(C(=O)Cc2ccccc2[N+](=O)[O-])CC1
b. O=C(CC1CCCC1)NCCS(=O)(=O)N1CCN(c2ccc(F)cc2)CC1
c. COc1ccc2c(=O)c3c(=O)n(-c4ccccc4)c(-c4ccco4)nc3oc2c1
Answer: a. O=C1CCN(C(=O)Cc2ccccc2[N+](=O)[O-])CC1
