$char ***P=ptr;$

$printf(“\%s”,**++P);$

**++P is done it  is incremented and points to second element which is s+2

printf("%s",**++p)

(p)-->600

(++P)-->602

(**)-->504

(%s)-->300=cone

Answer 1

Initially P is pointing to first element of  ptr array. When **++P is done it  is incremented and points to second element which is s+2 , which points to Cone. Hence C should be answer.

Answer 2

Option c is right.
