None of these

- Let's start by simplifying the expression: 43 × 45 + 43 × 55 - 43 × 30.

- Factor out 43: 43 × (45 + 55 - 30).

- Calculate the numbers inside the parenthesis: 45 + 55 - 30 = 70.

- Multiply 43 by 70: 43 × 70 = 3010.

- Option 1 is 3010.

Based on the above calculation, the expression equals 3010. So, the correct answer is:

- Option 1: 3010
