What is the minimum number of straight lines that is needed to construct the figure ?

• A. 11
• B. 13
• C. 15
• D. 21

Answer 1

The correct option is B 13

$\Rightarrow$ 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.

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

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