Answer:
A. It contains fewer volatile gases.
Explanation:
Mafic lava have a composition of about 45-55% silica with high amount of Fe, Mg, Ca.
The silica content is quite low compared to those of granitic magma whose silica content can reach up to about 60%.
What determines the viscosity of magma is basically the silica content of the magma and the temperature of the magma. Viscosity is the resistance to flow.
The higher the silica content, the lower the viscosity and the higher the amount of volatile gases. Such type of magma is the granitic magma. Granitic magma due to their viscosity flows slowly.
The lower the silica content, the higher the viscosity and the lesser the presence of volatile gases in them. Such an example is Mafic magma. Mafic magma flows very slowly with low amount of dissolved gases.
Those are called

The antibodies have epitopes that bind to the paratropes present on the antigens. When an antibody is made specifically to target a particular kind of antigen (say A), its epitope will be a structural compliment to the paratrope. When an antibody encounters two different antigens (say A and B) with structurally similar paratropes, it will bind specifically to A and non-specifically to B, as the antibody is not made in response to antigen B. This non-specific binding is referred to as blocking.
