Task: Answer the multiple choice question.
Query: Which compound has a 17.964\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(CCCCCNC(=O)N1CCn2c1nc1ccccc12)N[C@H](C(=O)O)c1ccccc1
[b] O=C(NCC(c1ccco1)N1CCN(c2ccccc2F)CC1)c1cccs1
Answer: a. O=C(CCCCCNC(=O)N1CCn2c1nc1ccccc12)N[C@H](C(=O)O)c1ccccc1
