The correct answer is "a maternal DQ α with a paternal DQβ".

This is because MHC II molecules are heterodimers, meaning they are composed of two different protein subunits. In humans, these subunits are encoded by the HLA-DQ and HLA-DP genes. Each person inherits one set of these genes from each parent, so they have both maternal and paternal versions.

During the process of antigen presentation, an antigen presenting cell (APC) can combine a DQ α chain from the mother with a DQ β chain from the father to form a functional MHC II molecule. This molecule can then bind to a peptide antigen and present it to a T cell, triggering an immune response.

The other options are not correct because they involve combining two α chains or two β chains, which would not result in a functional MHC II molecule. Also, the options "A and B" and "B and C" do not make sense in this context, as they do not specify any particular combinations of MHC II subunits.
