Answer 1

The correct option is A

Explanation

Statements 1 and 2 are correct: Coal formation began around 360 million to 290 million years ago. The build-up of silt and other sediments, together with tectonic movements, buried swamps and peat bogs often to great depths. With burial, the plant material was subjected to high temperatures and pressures. This caused physical and chemical changes in the vegetation, transforming it into coal.
