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 step by step, we will identify the metal and its oxide, and then write the reactions of the oxide with hydrochloric acid (HCl) and sodium hydroxide (NaOH).

### Step 1: Identify the Metal A
The question states that Metal A is used in the thermite process. The thermite process is a reaction that typically involves aluminum. Therefore, we can conclude that:

**Metal A = Aluminum (Al)**

### Step 2: Identify the Oxide B
