Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.139\% 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. CC(C)C(=O)NCCn1ccc2ccccc21
b. O/N=C1/C2C3CC4C5C3C1C5C1(OCCO1)C42
c. Clc1ccccc1CN1CCN(c2cccc3[nH]ccc23)CC1
d. CCOC(=O)C1=C(C)NC(C)=C(C(=O)OC)C1c1cccc(Cl)c1Cl
e. O=C(NCc1ccc(Cl)cc1)C1CCCO1
Answer: c. Clc1ccccc1CN1CCN(c2cccc3[nH]ccc23)CC1
