Task: Answer the multiple choice question.
Query: Which drug has a -26.025% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) Cn1c(=O)n(C)c2cc(NC(=O)c3ccccc3[N+](=O)[O-])c(Br)cc21
b) CCc1ccc(C(C)NC(=S)NC2CCCCC2)cc1
c) CCN1CCN(c2ccc(S(=O)(=O)N3CCCCC3)cc2NC(=O)c2ccc([N+](=O)[O-])o2)CC1
d) O=C(Nc1nc2n(n1)C(c1ccc(F)cc1)CC(c1ccccc1)N2)c1ccco1
Answer: a. Cn1c(=O)n(C)c2cc(NC(=O)c3ccccc3[N+](=O)[O-])c(Br)cc21
