Task: Answer the MCQ question.
Question: Which compound exhibits a 4.694\% 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: CCOc1cc(C2C(C(=O)c3ccco3)=C(O)C(=O)N2CC2CCCO2)ccc1O
b: C/C(CC(=O)Nc1ccccc1C#N)=N\NC(=O)c1ccncc1
c: CC(OC(=O)C1=COCCO1)C(=O)NC1CCCCC1C
d: CCOC(=O)N1CCN(C(=S)NC2CCCC2)CC1
Answer: a. CCOc1cc(C2C(C(=O)c3ccco3)=C(O)C(=O)N2CC2CCCO2)ccc1O
