The electric current is produced due to

Options

A. flow of electrons
B. flow of protons
C. flow of positive and negative charges
D. vibration of atoms

Explanation

**Step-by-Step Solution:**

1. **Understanding Electric Current**: Electric current is defined as the flow of electric charge. It is important to know what constitutes this charge.

2. **Identifying Charge Carriers**: In most conductive materials, particularly metals, the charge carriers are electrons. Electrons are negatively charged particles that can move freely within the material.

3. **Role of Protons**: Protons, which are positively charged, are generally fixed within the atomic structure of the material and do not move freely like electrons.
