Question

Match List I with List II and select the correct answer using the code given below the lists:

$$\begin{array}{cccc}& \text{List-I}& & \text{List-II}\\ \text{P.}& \text{Strainer.}& \text{1.}& \text{Reduce dross}\\ \text{Q.}& \text{Splash core.}& \text{2.}& \text{Separate lighter and heavier impurities}\\ \text{R.}& \text{Skim bob.}& \text{3.}& \text{Avoids aspiration}\\ \text{S.}& \text{Tapered sprue.}& \text{4.}& \text{Avoids and erosion}\end{array}$$

• A. $\begin{array}{cccc}\text{P}& \text{Q}& \text{R}& \text{S}\\ \text{1}& \text{4}& \text{2}& \text{3}\end{array}$
• B. $\begin{array}{cccc}\text{P}& \text{Q}& \text{R}& \text{S}\\ \text{1}& \text{3}& \text{4}& \text{2}\end{array}$
• C. $\begin{array}{cccc}\text{P}& \text{Q}& \text{R}& \text{S}\\ \text{2}& \text{1}& \text{3}& \text{4}\end{array}$
• D. $\begin{array}{cccc}\text{P}& \text{Q}& \text{R}& \text{S}\\ \text{2}& \text{1}& \text{4}& \text{3}\end{array}$

Answer 1

The correct option is A $\begin{array}{cccc}\text{P}& \text{Q}& \text{R}& \text{S}\\ \text{1}& \text{4}& \text{2}& \text{3}\end{array}$

Strainer - It Reduce dross

Splash core - It Avoids and erosion

Skim - Separate lighter and heavier impurities

Tapered sprue - It Avoids aspiration
