According to conservation of energy:

A Energy can be created from nothing

B Energy cannot be created or destroyed, only transformed

C Energy always increases in a system

D Energy is only conserved in space

✓ Correct Answer: Option B

The law of conservation of energy states that total energy in an isolated system remains constant — it can only change form.

💡 Why is B) the correct answer?

The correct answer to the question "According to conservation of energy:" is Option B: Energy cannot be created or destroyed, only transformed.

The other options — A) Energy can be created from nothing, C) Energy always increases in a system, D) Energy is only conserved in space — are incorrect for this Everyday Science question. As explained above: The law of conservation of energy states that total energy in an isolated system remains constant — it can only change form.
