Answer 1

Correct choice is (a) True

To elaborate: For a tumour to keep growing, it needs oxygen and food. Otherwise, the tumour will die out. Initially, the tumour takes in oxygen and nutrients from the surrounding or the same cells which causes necrosis. As it spreads out, it finally comes in contact with blood vessels which ensures that the tumour receives blood which provides it with oxygen and nutrients. Thus, the oxygen levels in the tumour regions are higher than normal.
