Task: Answer the multiple choice question.
Question: Which drug has a 11.082\% 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, b, c, or d without using any additional words.
Options:
a: COc1cccc(CN2CCN(C(=O)c3cccc(OC)c3)CC2)c1.O=C(O)C(=O)O
b: CCN1C(=O)N[C@@H](CCc2ccccc2)[C@H](C(=O)OC)[C@H]1C
c: CCOC(=O)C1CCN(c2ccccc2CN2CCN(c3ccccc3OCC)CC2)CC1
d: N=c1c(C(=O)NC2CCCC2)cc2c(=O)n3ccccc3nc2n1Cc1ccccc1Cl
Answer: b. CCN1C(=O)N[C@@H](CCc2ccccc2)[C@H](C(=O)OC)[C@H]1C
