Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 21.415% human ether-à-go-go related gene (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. O=C(CCNC(=O)c1ccco1)Nc1ccc(Cl)c(C(F)(F)F)c1
b. COc1ccc2[nH]c(C(=O)N/N=C/c3ccc(O)cc3O)cc2c1
c. O=C(O)C(=O)O.O=C(c1cccs1)N1CCN(Cc2ccncc2)CC1
d. ON=C1c2ccccc2-c2ccccc21
e. CN(Cc1ccccc1)C(=O)Cc1ccccc1
Answer: d. ON=C1c2ccccc2-c2ccccc21
