    After labelling the figure, we get the following,

    • Simplest triangles BGM, GHM, HAM, ABM, GIN, IJN, JHN, HGN, IKO, KLO, LJO, JIO, KDP, DEP, ELP, LKP, BCD and AFE (18)
    • Triangles with two components each ABG, BGH, GHA, HAB, HGI, GIJ, IJH, JHG, JIK, IKL, KLJ, LJI, LKD, KDE, DEL, and ELK (16)
    • Triangles with four components each BHI, GJK, ILD, AGJ, HIL and JKE (6)

    Total number of triangles in the figure is 18 + 16 + 6 = 40

    Also we need to count the number of squares in this figure,

    • Squares with two components each MGNH, NIOJ, and OKPL (3)
    • Squares with four components each BGHA, GIJH, IKLJ, and KDEL (4)

    Total number of squares in the figure is 3 + 4 = 7

    Hence option C is correct.
