**Explanation:**

The successor of a number is the number that comes after it. In this case, we are looking for the successor of 1 million.

**Understanding the place value system:**
To understand the successor, it is important to understand the place value system. In the place value system, each digit in a number has a specific place value based on its position. The place value increases from right to left, with each position being ten times the value of the position to its right.

For example:
- In the number 1, the digit 1 is in the ones place.
- In the number 10, the digit 1 is in the tens place and the digit 0 is in the ones place.
- In the number 100, the digit 1 is in the hundreds place, the digit 0 is in the tens place, and the digit 0 is in the ones place.

**Identifying the place value of 1 million:**
To find the successor of 1 million, we need to identify the place value of each digit in the number.

- In 1 million, the digit 1 is in the millions place.
- The following digits (zeros) represent the place values from hundred thousands to ones place.

**Finding the successor:**
To find the successor, we need to increase the value in the millions place by 1, while keeping the other digits unchanged.

In this case, the successor of 1 million would be:
- Increase the value in the millions place from 1 to 2.
- Keep the other digits (zeros) unchanged.

Therefore, the successor of 1 million is 2 million.

So, the correct answer is option 'A' - 2 million.

1 million = 10 lakhs
