Complete question is attached.
b) cell is the correct answer.
- The brightness of bulb in a circuit depends on two factors namely arrangement of components of circuit and the number of batteries or cells used in the circuit.
- Increase in cells or batteries will provide increased number of electrons to flow in the circuit, thus increasing the current and hence helping the bulb to glow brighter.
