Problem statement: Answer the multiple choice question.
Query: Which drug has a 5.244\% 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: O=C(CN1C(=O)NC2(CCCC2)C1=O)Nc1ccc(OC(F)(F)F)cc1
b: O=C(CN1CCC(n2nnc3cc(F)ccc32)CC1)Nc1ccc2c(c1)CCC2
c: O=C1NCCO1
d: C/C(=N/NC(=O)C(C)n1nc(C)c([N+](=O)[O-])c1C)c1ccc(OCC(N)=O)cc1
Answer: a. O=C(CN1C(=O)NC2(CCCC2)C1=O)Nc1ccc(OC(F)(F)F)cc1
