Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.455\% 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 additional words.
Options:
a.) O=C(OCC(=O)N1CCc2ccccc2C1)c1cccs1
b.) COc1ccc(-n2nc3cc(C)c(N)cc3n2)cc1Cl
c.) O=C(NCCCN1CCOCC1)C1CCN(S(=O)(=O)c2c(Cl)cccc2Cl)CC1
d.) CC(=NCCc1c(C)[nH]c2ccc(C)cc12)C1=C(O)CC(c2ccccc2)CC1=O
e.) CCC(CC)c1nc2ccccc2c(=O)[nH]1
Answer: b. COc1ccc(-n2nc3cc(C)c(N)cc3n2)cc1Cl
