Option D is the correct answer.
In option A, they are talking about surface tension of pheriphery. In the formula, we are talking about fluid. So, it's wrong.

Inversely proportional to Sp weight and (diameter) ^2.

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

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

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.
