B)7

An M dwarf star of mass 0.6 solar masses , a radius of 0.61 solar radii and a photospheric temperature of 3976 Kelvin . Assuming the dwarf contains the same mixture of elements as the Sun , and that the thermal pressure of the Sun's core is 1.3 x 10 ^ 14 N / m ^ 2 estimate the ratio between the thermal pressure in the M dwarf's core versus that of the Sun .
