Task: Answer the MCQ question.
Query: Which drug has a 23.554\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(Nc1nc(-c2cc(F)ccc2F)cs1)C1=COCCO1
b O=C(COC(=O)c1ccc([N+](=O)[O-])s1)NCc1ccc(F)cc1
c COc1ccc(-c2c(=O)n(OCc3nc4ccccc4[nH]3)c3ccccc3[n+]2[O-])cc1
Answer: b. O=C(COC(=O)c1ccc([N+](=O)[O-])s1)NCc1ccc(F)cc1
