Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.093\% 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(N/N=C1/CC2C=CCC12)c1ccc(Br)o1
b: O=C(N/N=C/c1cccs1)C1COc2ccccc2O1
c: Br.CCC(=O)Nc1nc(C)c(-c2csc(Nc3cccc(O)c3)n2)s1
d: CC(=O)c1coc2ccc(OCCN3CCCCC3)cc12
Answer: b. O=C(N/N=C/c1cccs1)C1COc2ccccc2O1
