Question
The image depicts a structural truss with joints and members labeled A, B, C, and D. The truss is subject to a load "P" at point D, which is vertically aligned. 

### Description of the Truss Geometry:
- **Points A and C** are located on a horizontal plane at the same vertical level.
- **Point D** is located on the vertical line of action of the force P, with horizontal distances from A and C: 
  - \(AD = a\)
  - \(CD = a\)
- The vertical distance from point A to D is divided into segments:
  - **\( \frac{1}{4}a \)** from the base to C
  - **\( \frac{3}{4}a \)** from C to D

### Analyzing Forces:
To find the force in member CD, consider the equilibrium of the truss, typically using method of joints or sections. 

### Question:
"Which of the following is closest to the force in member CD?"

To solve for the force in member CD, consider the equilibrium criteria and use methods such as the method of joints or method of sections, considering static determinations principles.
