What would most likely happen if capillaries had thick walls and large diameters?

The blood cells flowing through them would form clots along their walls that block flow to tissue.

The blood cells flowing through them would not be able to exchange gas with surrounding tissue.

The blood cells would flow slowly through them, preventing them from carrying oxygen to tissue.

The blood cells would flow quickly through them, allowing them to carry more oxygen to tissue.
