Match all the possible combinations between **Column X (Cement compounds) **and **Column Y (Cement properties):**

$$\begin{array} {|l|l|} \hline \textbf{Column X} & \qquad \textbf{Column Y} \\\hline \text{(i) C}_{3} \text{S} & \text{(P) Early age strength} \\\hline \text{(ii) C}_{2} \text{S} & \text{(Q) Later age strength} \\\hline \text{(iii) C}_{3} \text{A} & \text{(R) Flash setting} \\\hline & \text{(S) Highest heat of hydration} \\\hline & \text{(T) Lowest heat of hydration} \\\hline \end{array}$$

Which one of the following combinations is correct?

- $\text{(i) – (P), (ii) – (Q) and (T), (iii) – (R) and (S)}$
- $\text{(i) – (Q) and (T), (ii) – (P) and (S), (iii) – (R)}$
- $\text{(i) – (P), (ii) – (Q) and (R), (iii) – (T)}$
- $\text{(i) – (T), (ii) – (S), (iii) – (P) and (Q)}$
