Hint:

Common flame colours: Na \(\rightarrow\) Yellow Li \(\rightarrow\) Crimson red Ca \(\rightarrow\) Brick red Ba \(\rightarrow\) Apple green

Answer 1

The Correct Option is C

Concept: Flame test is used for identifying metal ions by their characteristic flame colours.

Step 1: Recall the flame colour of sodium.
Sodium imparts a bright yellow colour. \[ Na \rightarrow \text{Yellow} \] \[ A \rightarrow II \]

Step 2: Recall the flame colour of calcium.
Calcium produces brick-red colour. \[ B \rightarrow III \]

Step 3: Recall the flame colour of barium.
Barium gives apple-green colour. \[ C \rightarrow I \]

Step 4: Recall the flame colour of lithium.
Lithium gives crimson-red colour. \[ D \rightarrow V \] Thus, \[ A-II,\quad B-III,\quad C-I,\quad D-V \] \[ \boxed{\text{Option (C)}} \]
