Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 10.996\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(Cc1ccccc1[N+](=O)[O-])N1CCN(c2ccc(F)cc2)CC1
[b] COc1ccc(-n2nc(C(=O)NCC(=O)NC3CCCCCC3)c3ccccc3c2=O)cc1OC
[c] COc1ccc(C(=O)NCc2ccc(Cl)c(Cl)c2)cc1OC
[d] COc1ccc(CNC(=O)CN(c2ccc(OC)cc2)S(=O)(=O)c2c(C)nn(C)c2C)cc1
[e] Cc1ccc(C(=C2C3C=CC2C2C(=O)NC(=O)C32)c2ccc(C)cc2)cc1
Answer: a. O=C(Cc1ccccc1[N+](=O)[O-])N1CCN(c2ccc(F)cc2)CC1
