**Answer: c) 25.9%**

Explanation:

Given Data:• Void ratio, e = 0.35

Solution:The formula of porosity in terms of the void ratio is,

n = e / 1+e

Where,

• n = Porosity of soil

• e = Void ratio∴ n = 0.35 / (1 + 0.35)

∴ n = 0.35 / 1.35

∴ n = 0.259

∴ n = 25.9%Hence, the value of porosity of soil is 25.9%
