A metal A, which is used in thermite process, when heated with oxygen gives an oxide B, which is amphoteric in nature. Identify A and B. Write down the reactions of oxide B with HCl and NaOH. 

Explanation

To solve the question, we will identify the metal A and its oxide B, and then write down the reactions of oxide B with HCl and NaOH.

### Step 1: Identify Metal A
The metal used in the thermite process is **Aluminum (Al)**.

**Hint:** The thermite process typically involves metals that can reduce metal oxides, and aluminum is a common choice due to its strong reducing properties.

### Step 2: Identify Oxide B
