To find the number of defective bulbs produced each day, we need to calculate 2 out of every 10 bulbs produced.

Given that the factory produces 820 bulbs per day, we can use the concept of proportions to find the number of defective bulbs.

Let's set up the proportion:

2 defective bulbs / 10 total bulbs = x defective bulbs / 820 total bulbs

To solve for x, we can cross-multiply:

(2 defective bulbs) * (820 total bulbs) = (10 total bulbs) * (x defective bulbs)

1640 defective bulbs = 10x defective bulbs

Now, we can solve for x by dividing both sides of the equation by 10:

1640 defective bulbs / 10 = 10x defective bulbs / 10

164 defective bulbs = x defective bulbs

Therefore, the number of defective bulbs produced each day is 164.

Hence, the correct answer is option C) 164.
