Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -6.425\% 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, or d without using any other words.
Options:
a: CCCNC(=O)C1(CC2CC(c3ccccc3)=NO2)CCN(C(=O)OC(C)(C)C)CC1
b: CC1CCN(S(=O)(=O)c2cccc(C(=O)Oc3ccc([N+](=O)[O-])cc3)c2)CC1
c: COc1cc(C2C3=C(CCCC3=O)Nc3c2c(C)nn3-c2cccc(C)c2)cc(OC)c1O
d: Cc1nc(-c2ccccc2)sc1C1(C)CC(c2cccc([N+](=O)[O-])c2)=NO1
Answer: a. CCCNC(=O)C1(CC2CC(c3ccccc3)=NO2)CCN(C(=O)OC(C)(C)C)CC1
