Task: Answer the MCQ question.
Query: Which compound exhibits a -0.029\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) COc1ccc(C2C(C(C)=O)=C(O)C(=O)N2c2nccs2)cc1
b.) Cn1cc(SCC(=O)Nc2nc3ccccc3s2)c2ccccc21
c.) CCS(=O)(=O)Nc1ccc(C2=NN(C(=O)c3ccccc3)C(c3cccs3)C2)cc1
d.) Cc1cc(C)nc(N2CCC(C(=O)NNC(=O)c3ccccc3)CC2)n1
Answer: a. COc1ccc(C2C(C(C)=O)=C(O)C(=O)N2c2nccs2)cc1
