Best answer
Right answer is (a) True

Easiest explanation: Total internal reflection microscopy (TIRF) is a specialized type of laser-based fluorescence microscopy, which allows the focusing of very thin planes. As a result, fluorescent light rays emanating from the field of view do not obscure the specific proteins being monitored.
