The correct option is A are randomly scattered.
∙ In broadcast planting, seeds are scattered randomly by farmers in loosened soil. As it is done manually, the seeds might not be sown at a proper depth and at equal distances. As no machines are involved in this process, it is cheap compared to other methods.
∙ Post the scattering, these seeds are not covered. And, because of this, they are picked and eaten by birds which is a major disadvantage.
