B Correct answer
Explanation

Silicon dioxide (SiO2) is the standard gate insulating material in MOSFETs. It forms naturally as a high-quality oxide on silicon surfaces, providing excellent insulating properties with minimal defects. Silicon dioxide's compatibility with silicon processing and its ability to form a stable interface with silicon makes it the ideal choice for MOSFET gate insulation.
