Solution

The correct option is B Laser photobleaching
Fluorescence recovery after photobleaching (FRAP) is an optical technique capable of quantifying the two-dimensional lateral diffusion of a molecularly thin film containing fluorescently labelled probes or to examine single cells. This technique is very useful in biological studies of cell membrane diffusion and protein binding. Therefore, the correct answer is option B.
