Task: Answer the multiple-choice question.
Question: Which compound exhibits a 12.679\% 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, or c without using any other words.
Options:
a COc1ccc(-c2c(C)nn3c(N4CCC(C(=O)NCCN(C)C)CC4)cc(C)nc23)cc1OC
b COCCCNC(=S)N/N=C/c1cccc(OC)c1O
c C=CCn1c(SCc2nnc(-c3ccccc3)o2)nnc1C(O)c1ccccc1
Answer: b. COCCCNC(=S)N/N=C/c1cccc(OC)c1O
