    Answer : Option B

    Explanation :

    The figure may be labelled as shown.

    The horizontal lines are AE and JF i.e. 2 in number. The vertical lines are AJ, CH and EF i.e. 3 in number.

    The slanting lines are AG, BF, JD, IE, AB, DE, JI and FG i.e. 8 in number.

    Total number of straight lines needed to construct the figure = 2 + 3 + 8 = 13.
