    Answer:

    d ) 12

    Explanation:

    i. As line can have infinite number of dots, we will not take it in consideration here as it is possible with any no. of dots except a single dot.

    ii. Now, triangle have 3 vertices and rectangle have 4, so the no. of dots required to be arranged in these form, needs to be the LCM of 3 and 4, which is 12.

    iii. So, 12 is the answer.

    HOPE THIS IS HELPFUL !!! : )

    d. 12

    Explanation :

    No. of sides in a line = 2

    No. of sides in a triangle = 3

    No. of sides in a rectangle = 4

    So, the number which can be arranged in all three ways must be the LCM of the given numbers (2, 3, 4) = 12
