Match the processes of product development with their characteristics.

Step 1: Product synthesis (P).
Product synthesis involves creating or formulating the initial product concept. This aligns with:
\[
2\; \text{Process related to design conceptualization}
\]
Thus, \(P \rightarrow 2\).
Step 2: Product simplification (Q).
Simplification focuses on reducing the number of components without compromising functionality. This exactly matches:
\[
4\; \text{Reducing parts without losing functionalities}
\]
Thus, \(Q \rightarrow 4\).
Step 3: Product analysis (R).
Analysis evaluates the conceptual design to convert it into an engineering model. This matches:
\[
1\; \text{Conversion of conceptual design into engineering model}
\]
Thus, \(R \rightarrow 1\).
Step 4: Product standardization (S).
Standardization ensures product consistency and uniformity. Therefore:
\[
3\; \text{Maintaining uniformity and consistency}
\]
Thus, \(S \rightarrow 3\).
Final mapping:
\[
P-2, Q-4, R-1, S-3
\]
This matches option (A).
Final Answer: (A)
A through hole of 10 mm diameter is to be drilled in a mild steel plate of 30 mm thickness. The selected spindle speed and feed for drilling hole are 600 revolutions per minute (RPM) and 0.3 mm/rev, respectively. Take initial approach and breakthrough distances as 3 mm each. The total time (in minute) for drilling one hole is ______. (Rounded off to two decimal places)
In a cold rolling process without front and back tensions, the required minimum coefficient of friction is 0.04. Assume large rolls. If the draft is doubled and roll diameters are halved, then the required minimum coefficient of friction is ___________. (Rounded off to two decimal places)
