Task: Answer the multiple-choice question.
Query: Which compound exhibits a -42.505% 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, or c without using any additional words.
Options:
a) Cc1cccc(CCNC(=O)CN(C)S(=O)(=O)c2cnc[nH]2)c1
b) Cc1ccccc1-c1nc(CN2CCC(C(=O)N3CCN(c4ccccn4)CC3)CC2)c(C)o1
c) C=CCOC(=O)C1=C[C@H](c2coc3ccccc3c2=O)C[C@H](OCCCCO)O1
Answer: c. C=CCOC(=O)C1=C[C@H](c2coc3ccccc3c2=O)C[C@H](OCCCCO)O1
