The correct option is B.
The restriction of the domain is made so that the denominator is never zero and the expression is never undefined. In case of such questions, domain must be taken into account.

Answer:
Option d is correct.
Equation : P=7n+20.
Explanation;
Given the perimeter of each figure is;
Perimeter of triangle is equal to the sum of all the sides of a triangle.
Perimeter of 1 triangle is 21
Perimeter of 2 triangle is 34 and
Perimeter of 3 triangle is 41
Let n be the number of figure and P be the perimeter of the figure;
the only equation which satisfy the given perimeter is;
Check:
for n =1 which means 1 triangle then;
for n = 2 , [ i.e 2 triangle]
and for n =3 [i.e, 3 triangles]
Therefore, the equation P =7n+20 relates the number of triangles in the figure(n) to the perimeter of the figure(P).
