Chromosomal mutation occurs due to physical effects. It happens as a result of an error in cell division which is considered as the physical effect. Chromosome aberrations are usually caused by a failure of chromosome division, which results in cells with an extra chromosome or a deficiency in chromosomes. So, the correct answer is'Physical effects'. Hope it helps you?
