Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.662\% 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: NC(=O)CC(NC(=O)Cc1ccc(Br)cc1)c1ccc(N2CCN(c3ccccn3)CC2)c([N+](=O)[O-])c1
b: O=C(CSc1nc2ccccc2c(=O)n1-c1ccc(OC(F)F)cc1)NCc1cccs1
c: COc1ccc(-n2nc(C(=O)NCC(=O)NCCCN3CCCCCC3)c3ccccc3c2=O)cc1Cl
d: Cc1ccc(-c2cc3nc(-c4ccc(Br)cc4)cc(N)n3n2)cc1
e: COCCNC(=O)C(c1cccs1)N(Cc1ccccc1)C(=O)Cn1nnc2ccccc21
Answer: b. O=C(CSc1nc2ccccc2c(=O)n1-c1ccc(OC(F)F)cc1)NCc1cccs1
