Explanation:

Let’s break this down:

- Here’s the key part: After the certifying officer gets suggestions or objections from the trade union or workmen, their next move is to certify the standing orders (after any tweaks).

- They have to send copies of the certified standing orders to both the employer and the trade union (or workmen).

- By law—specifically under the Industrial Employment (Standing Orders) Act—they need to do this within seven days.

- So, your options:

1. Three days – That’s too short, not what the law says.

2. Seven days – This is spot on.

3. Fifteen days – That’s too long.

4. One month – Way too long.

Correct Answer: Option 2, seven days.
