Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 8.582\% hERG inhibition at 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(Cl)cn1)c1ccc2c(Cl)c3c(nc2c1)CCC3
b: O=C(NNC(=O)c1ccccc1Br)c1ccc2nc[nH]c2c1
c: CCc1cccc(C)c1NC(=O)Cn1nc(C)n2cccc2c1=O
d: CCN1CCN(C(=O)c2ccc3c(c2)N(Cc2ccc(C)cc2)CCS3)CC1
Answer: b. O=C(NNC(=O)c1ccccc1Br)c1ccc2nc[nH]c2c1
