Question

Match the following: \begin{center} \renewcommand{\arraystretch}{1.5} \begin{tabular}{|c|c|c|c|} \hline \multicolumn{2}{|c|}{List I (Alloy)} & \multicolumn{2}{c|}{List II (Use)}
\hline A & Li-Pb & I & In aircraft construction
B & Be-Cu & II & To make bearings for motor engines
C & Mg-Al & III & To make tetraethyl lead
D & Na-Pb & IV & To make high strength springs
\hline \end{tabular} \end{center} \vspace{0.5cm}

• A. A-II; B-IV; C-III; D-I
• B. A-II; B-IV; C-I; D-III
• C. A-IV; B-I; C-II; D-III
• D. A-III; B-II; C-I; D-IV \vspace{0.5cm}

Hint:

When matching lists, focus on the specific properties or common uses associated with each item to determine the correct match.

Answer 1

The Correct Option is B

Each alloy is correctly paired with its most common application: \begin{itemize} \item A (Li-Pb): Used to make bearings for motor engines. \item B (Be-Cu): Used to make high strength springs. \item C (Mg-Al): Used in aircraft construction due to its lightweight and high strength. \item D (Na-Pb): Used to make tetraethyl lead. \end{itemize} \vspace{0.5cm}
