Solution

The correct option is B $3 m, 4 m, 8 m$
A triangle with three sides a,b and c will be possible when:
$a + b > c$
$b + c > a$
$a + c > b$
$H e r e, a = 2, b = 3, c = 4$
$2 + 3 > 4$
$3 + 4 > 2$
$2 + 4 > 3$
$∴ A) i s p o s s i b l e .$
$H e r e, a = 3, b = 4, c = 8$
$3 + 4 = 7$
$7 < 8$
$∴ a + b > c i s n o t s a t i s f i e d .$
$C) & D) w i l l a l s o b e p o s s i b l e .$
$∴ B) C o r r e c t a n s w e r .$
