Task: Answer the multiple choice question.
Query: Which drug has a 28.073% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a COc1cc(-c2nc3ccccn3c2/N=C/c2ccccc2)ccc1O
b CCCc1cc(=O)oc2c3c(cc(OCC(=O)N[C@@H](C)C(=O)O)c12)OC(C)(C)CC3
c CCc1cccc(CC)c1NC(=O)COC(=O)c1ccccc1-c1nc2ccccc2s1
d COCCCn1c(N)c(C(=O)OCCOC)c2nc3ccccc3nc21
e COc1cccc(CC(=O)OCC(=O)NC2(C#N)CCCCC2)c1
Answer: b. CCCc1cc(=O)oc2c3c(cc(OCC(=O)N[C@@H](C)C(=O)O)c12)OC(C)(C)CC3
