Solution
The correct option is C Neurons
All cells usually have a fixed life span. The cells divide for a certain period of time, after which they die. This has been explained by the phrase "programmed cell death". The lifespan of each type of the body cells differ and it depends on the function it is destined to perform. Neurons are long lived and are generally non-mitotic. Memory T cells and memory B cells can provide long lasting immunity from exposure to antigens, they too are long lasting but their life span is less than that of a neuron.The lifespan of RBC is shortest amongst the options which are given, it is 115 days. Thus, the correct answer is option D.
