C.
D.

Explanation

To find the symbolic representation of a photodiode, we can follow these steps:

### Step 1: Understand the Components of a Photodiode
A photodiode is a semiconductor device that converts light into an electrical current. It consists of a p-n junction, similar to a regular diode, but it is designed to be sensitive to light.

### Step 2: Identify the Symbol for a Diode
The basic symbol for a diode consists of a triangle pointing towards a line. The triangle represents the anode (p-side) and the line represents the cathode (n-side).

### Step 3: Modify the Diode Symbol for a Photodiode
To represent a photodiode, we typically add arrows to the diode symbol to indicate the direction of incoming light. This shows that the device operates based on light exposure.

### Step 4: Finalize the Symbol
The final symbolic representation of a photodiode looks like a diode symbol with arrows pointing towards it, indicating that it is sensitive to light.

### Conclusion
The symbolic representation of a photodiode is a diode symbol with arrows indicating light incidence.
