Problem statement: Answer the multiple choice question.
Query: Which drug has a 12.221\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=[N+]([O-])c1ccc(-n2nnnc2CN2CCOCC2)cc1
b: CS(=O)(=O)NNC(=O)Cn1nnc(-c2ccc(OCc3ccccc3Cl)cc2)n1
c: O=C(COc1ccc(Cl)cc1Cl)Nc1ccc(C(=O)Nc2ccccc2C(=O)O)cc1
d: Cc1cccc(N2CCN(S(=O)(=O)c3ccc4c(c3)NC(=O)CS4)CC2)c1C
e: Br.Nc1nc2c(s1)CCc1ccccc1-2
Answer: a. O=[N+]([O-])c1ccc(-n2nnnc2CN2CCOCC2)cc1
