Problem statement: Answer the multiple-choice question.
Query: Which drug has a 4.068\% 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 additional words.
Options:
a. O=C(Nc1ccc(-c2nc3ccccc3[nH]2)cc1)c1ccccc1NS(=O)(=O)c1ccc(F)cc1
b. CCCCn1c(N)c(NCCC(C)C)c(=O)[nH]c1=O
c. COc1ccccc1NS(=O)(=O)c1ccc(N/N=C/C=C/c2ccccc2[N+](=O)[O-])c([N+](=O)[O-])c1
d. Cn1cc(S(=O)(=O)Nc2ccc(Oc3ccccc3)cc2)c(=O)n(C)c1=O
Answer: b. CCCCn1c(N)c(NCCC(C)C)c(=O)[nH]c1=O
