Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.586\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a C=CCn1c(O)c(CN2CCCCC2)c(C)c(C#N)c1=O
b CCC1=NN(C(=O)Cc2ccc(OC)cc2)C(O)(C(F)(F)F)C1
c COc1ccccc1N1CCN(CC(=O)Nc2nc(C)c(C(=O)N(C)C)s2)CC1
d CSCCC(=O)N1CC[C@@H](N2CCN(c3ccccc3F)CC2)[C@H](O)C1
e O=C(O)CSc1nc2ccccc2o1
Answer: b. CCC1=NN(C(=O)Cc2ccc(OC)cc2)C(O)(C(F)(F)F)C1
