Task: Answer the MCQ question.
Query: Which drug exhibits a 6.367\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(Nc1ccc2c(c1)OCO2)C1CCN(S(=O)(=O)c2ccc3c(c2)OCCO3)CC1
b: COc1ccc(-c2cc(C(=O)NN)n(-c3ccccc3)n2)cc1
c: Cc1ccc(OCc2ccccc2C)c([N+](=O)[O-])n1
d: CCOC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCCN(C)C)C2c2cccnc2)c1C
Answer: d. CCOC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCCN(C)C)C2c2cccnc2)c1C
