Capillarity is due to rise and fall of liquid. I. E cohesion and adhesion. And we know h=4σcosθ/wr hence is inversely proportional to diameter. Hence option D is correct.
Where surface tention means force per unit lenght and it is due to cohesion only. Hence it does not take in part of rise and fall of liquid so option A can't be considered.

h=(4sigma cosθ) ÷(wd).
Here, h Inversely proportional to sp. Weight of liquid.

It should be "inversely proportional to the specific weight of liquid".
