Correct option is B
A tee joint is a type of welded joint where two plates or components are joined at approximately a right angle, forming a "T" shape. One plate is typically vertical (web) and the other horizontal (flange), and the weld is applied along the intersection to connect the two. This is different from a lap joint, where the plates overlap each other. Tee joints are commonly used in structural frames, machine frames, and supporting members.
