Array, accessing array, C programming

Question

Should this question be invalid? 

t[4] Mentions 4 elements, but question assigns 5 elements.
Because according to my knowledge accessing element t[4] (if we consider index to be from 0 to 4, also it's by default in C) should give out of bound error.
Answer for this question was 'Option C'.

Answer 1

It is a printing mistake in question it should be t[5]

The correct answer will be C

Answer 2

Answer will be Option D :  4 3 0 1 2

Explanation :

t[0]=2; t[1]=3; t[2]=4 ; t[3]=1 ; t[4]=0;

for i=0 : t[t[t[i]]] = t[i]  , here t[t[t[i]]] means t[4] which is  2, as t[0]=2;

for i=1 : t[t[t[i]]] = t[i]  , here t[t[t[i]]] means t[1] which is  3, as t[1]=3;

for i=2 : t[t[t[i]]] = t[i]  , here t[t[t[i]]] means t[0] which is  4, as t[2]=4;

for i=3 : t[t[t[i]]] = t[i]  , here t[t[t[i]]] means t[3] which is  1, as t[3]=1;

for i=4 : t[t[t[i]]] = t[i]  , here t[t[t[i]]] means t[2] which is  0, as t[4]=0;

Compiler should give error because excess elements

warning: excess elements in array initializer

I checked it from Compiler

Answer 3

c option beacause their was only change when for loop run  first time for i= 0 t[ t [t [i] ] ] = t[i]

then t[4] = 2

and for i= 1,2,3,4 loop will run but no change occur in the array

so they printed 2,3,4,1,2
