Task: Answer the multiple choice question.
Query: Which drug has a 5.631\% 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 additional words.
Options:
a: Cc1ccc2nc3c(cc(C(=O)NC4CCCC4)c(=N)n3C3CCCCC3)c(=O)n2c1
b: CCN(CC(=O)NCc1cccs1)C(=O)/C=C/c1cccc(OC)c1OC
c: Cc1nonc1C1CCCN1C(=O)c1cc(COc2cccc(C(F)(F)F)c2)on1
d: O=C(CN1C(=O)/C(=C/c2ccccc2F)Sc2ccccc21)NCC1CCCO1
e: CN(C)S(=O)(=O)N1CCC(Oc2ccc(C(=O)NC3CCCCC3)cc2)CC1
Answer: b. CCN(CC(=O)NCc1cccs1)C(=O)/C=C/c1cccc(OC)c1OC
