Explanation:

Certainly! Let's solve the given problem.

- The dimensions of the park are 120 m long and 104 m wide.

- A 1 m wide path runs inside the boundary, which makes the area inside the path 2 m less in each dimension (since the path runs along all four sides).

- So, the inside dimensions are (120 - 2) m by (104 - 2) m, equal to 118 m by 102 m.

- The length of the inside edges to be marked is the perimeter of this inside rectangle.

- The perimeter is calculated as 2 * (Length + Width), which equals 2 * (118 + 102) = 2 * 220 = 440 meters.

- The cost of marking each meter is Rs.2.50, so the total cost would be 440 meters * Rs.2.50/meter = Rs.1100.

Therefore, the correct option is:

- Option:4 - 1100
