B Correct answer
Explanation

The total volume is 1 ml + 19 ml = 20 ml. The percentage of salt is (1 / 20) * 100 = 5%.

AI explanation

The total volume of the new dilution is the sum of the salt and distilled water, which is 1 ml plus 19 ml to equal 20 ml. To find the percentage of salt, divide the salt volume by the total volume and multiply by 100. The calculation is 1 divided by 20 multiplied by 100, which gives a salt percentage of 5 percent.
