For the abve question the answer is C

c. template <class T>
T search(T array[], int start, T target, int size);

Justification:

* The search function can return any generic type.(so T search(..))

* the array to search may contain integer or long or .. and similarly target to search can also occur as any return type so T search(T array[], .. , T target,..)

* the size and start should be a integer, no generic type needed for start and size so declared as int ( T search(T array[], int start, T target, T size)

However, Option c suits the given problem .. all the options will work without any errors but type casting may needed in some cases.
