K = G. L/A
10–3 × 2.768 = 1/R ×L/A
L/A = 228.08 × 10–3
= 0.2281 cm–1

Given:
- Concentration of KCl solution (c) = 0.02 M
- Specific conductance (k) = 2.768 × 10^-3 ohm^-1 cm^-1
- Resistance of the cell (R) = 82.4 ohm

We need to calculate the cell constant.

Formula:
- Conductance (G) = 1/R
- Conductivity (σ) = k/l
- Concentration (c) = n/V

Where,
- l = length of the cell
- n = number of moles of solute
- V = volume of the solution

Calculation:
- From the formula of conductance, G = 1/R = k/l × c
- Solving for l, l = k/(c × R)
- Substituting the given values, l = (2.768 × 10^-3) / (0.02 × 82.4) cm
- l = 0.003408 cm

- Therefore, the cell constant = 1/l = 1/0.003408 cm
- Cell constant = 293.57 cm^-1
- Rounding off the value to four significant figures, the cell constant = 0.2281 cm^-1

Hence, the correct answer is option 'B'.
