{'distribution': [0, 0, 1, 0], 'work hours': [0, 1, 1, 0], 'percentage': [1, 2, 2, 3], 'workers': [2, 1, 6, 18], 'table': [0, 0, 1, 0], 'hours': [7, 2, 16, 9], 'more hours': [0, 1, 1, 0]}

The correct answer is option 4: 43-75.

To find the percentage of workers who worked for 40 or more hours, we need to calculate the total number of workers who worked for 40 or more hours and divide it by the total number of workers in the factory.

From the given table, we can see that there are 15 workers who worked for 40-44 hours and 20 workers who worked for 45-50 hours.

Therefore, the total number of workers who worked for 40 or more hours is 15 + 20 = 35.

To find the percentage, we divide 35 (the number of workers who worked for 40 or more hours) by the total number of workers in the factory, which is the sum of all the workers in the table: 20 + 15 + 25 + 16 + 4 = 80.

Calculating the percentage:

(35 / 80) * 100 = 43.75

So, the correct answer is option 4: 43-75.
