Answer:

0.9 grams

Explanation:

Given that

NaCl solution = 0.9%

And, the milliliters of solution = 100

So, the computation of the Nacl included is shown below:

As We assume that

The  1 gram ÷ 100 gram = 1%

So we assume the number of grams be X

So, now the equation is

So, the X gram is

= 0.9% × 100 ml

= 0.9 grams

Hence, the correct answer is D. 0.9 grams
