d) iv. m
There are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.
<h3>
Current in the circuit</h3>
The current in the circuit is determined by applying Ohms law as shown below;
V = IR
where;
- I is the current
- V is the voltage
- R is the resistance
I = V/R
At a constant resistance of the circuit, the current in a circuit will increase when the emf of the circuit increases.
Thus, we can conclude that, there are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

Answer:
This is due to refraction of light
Explanation:
When a straw is placed in a glass it appears to be broken as a result of refraction of light on the air-water interface.
Since, the refractive index of water is more than that of glass.
Also, water is denser than air, which means light travels slower in water than in air.
Most importantly, When light travels from rarer to denser medium it bents towards the normal and deviates from its original path which explains the broken view of straw in a glass of water.
