Task: Answer the multiple choice question.
Query: Which compound exhibits a 8.978\% 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 additional words.
Options:
a) CC(=O)Nc1ccc(S(=O)(=O)N(C)CC(=O)OC(C)C(=O)N(C)Cc2ccccc2)cc1
b) O=C(c1cc(-c2ccncc2)nc2ccc(Br)cc12)N1CCN(c2ccccn2)CC1
c) CCOC(=O)/C(C#N)=C/Nc1ccsc1C(=O)OC
Answer: c. CCOC(=O)/C(C#N)=C/Nc1ccsc1C(=O)OC
