Explanation:

Let's break down the statements:

- The Index of Industrial Production (IIP) in India measures the growth of three main industry groups:

- Mining

- Manufacturing

- Electricity

- "Gas and Water connection" is not one of the sectors included in the IIP.

- Therefore, amongst the given options, the sector not included is "Gas and Water connection".

OPTIONS:

1. 1 and 2 Only

2. 2 and 3 Only

3. 1, 3 and 4 Only

4. 3 only

5. All of the above

Explanation of options:

- Option 1 includes Mining as not part of IIP, which is incorrect.

- Option 2 and 3 include correct and incorrect sectors mixed together.

- Option 4 is wrong, as Manufacturing (3) is actually part of IIP.

- Option 5 is wrong, as not all are excluded.

The correct answer is: Option 1: 1 and 2 Only

Because only "Gas and Water connection" is not a broad sector of IIP—Mining, Manufacturing, and Electricity are part of IIP.
