converting decimal number to binary, initially we push all the binary digits formed into the stack. After the entire number has been converted into the binary form, we pop one digit at a time from the stack and print it. Therefore we get the decimal number converted into its proper binary form.

its STACK because to convert a decimal no into binary we need continuous divisiion by 2
the result is calculated by writing the remainders in opposite order i.e. LIFO so stack.

answer is stack.
solution is:-
when the remainders are stored while decimal to binary conversion, they are stored using LIFO technique in stack.
example:- 24-decimal number, divide it by 2 i.e. 24%2=0 rem is stored in stack. now, 12%2=0 rem is stored in stack again. so, in stack they are stored as 000110. but to pop the remainders stored, they are popped from stack using same LIFO technique but in reverse order i.e. 011000. so, the answer is (b) Stack.
