(B) The statement is False.
Let the radii of the two circles be $r_1$ and $r_2$,and the lengths of the arcs be $l_1$ and $l_2$. Given that the arc lengths are equal,we have $l_1 = l_2 = l$.
The formula for the length of an arc is $l = r \theta$,where $\theta$ is the angle in radians.
The area of a sector is given by $A = \frac{1}{2} r^2 \theta$.
Since $l = r \theta$,we can write $\theta = \frac{l}{r}$.
Substituting this into the area formula,we get $A = \frac{1}{2} r^2 (\frac{l}{r}) = \frac{1}{2} rl$.
For two different circles with the same arc length $l$,the areas are $A_1 = \frac{1}{2} r_1 l$ and $A_2 = \frac{1}{2} r_2 l$.
Since the circles are different,their radii $r_1$ and $r_2$ are not equal $(r_1 \neq r_2)$.
Therefore,$A_1 \neq A_2$. Thus,the areas are not necessarily equal.
