In the curdling of milk, the process involves the conversion of milk casein into paracasein through the action of rennin (also known as chymosin or renin enzyme), followed by the formation of calcium paracaseinate. So, in this process:

'Y' denotes Renin (or chymosin), which is an enzyme responsible for converting milk casein into paracasein.
'Z' denotes Ca^{++} (Calcium ions), which play a crucial role in the formation of calcium paracaseinate during the curdling process.
So, the correct answer is option D: Renin and Ca^{++}.
