Answer

To solve the question "Which of the following resins produces sparks?" we will analyze the options provided and identify the correct answer step by step.

### Step 1: Understand the Options
The options given are:
- A) Gum
- B) Umber
- C) Both A and B
- D) None of these

### Step 2: Analyze Each Resin
- **Gum**: This resin does not typically produce sparks when rubbed against fur or other materials.
