This question was addressed to me in final exam.

This interesting question is from Castellated Beams & Lintels in section Design of Beams of Design of Steel Structures

Answer 1

The correct option is (a) rectangular load

To explain: When the slab over lintel is below apex of equilateral triangle formed on lintel, the load of masonry in the rectangle is considered. The load of masonry in the rectangle is assumed to act over by taking length equal to span of lintel and height equal to clear height of slab above the lintel.
