Task: Answer the multiple choice question.
Query: Which drug has a 0.505\% 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. Cc1c(CBr)[n+](=O)c2c(n1[O-])C(Br)CCC2Br
b. CC1=NN(c2ccccc2)C(=O)/C1=C/c1cccc(C)c1
c. COc1cccc(NC(=S)NNC(=O)CCn2cc([N+](=O)[O-])cn2)c1
d. O=[N+]([O-])c1cccc(NC(=S)N2CCN(c3ccccn3)CC2)c1
Answer: b. CC1=NN(c2ccccc2)C(=O)/C1=C/c1cccc(C)c1
