Answer:
Taking reading of the volume level of liquid in a buret while it is inclined leading to parallax error
Explanation:
Practices that will not help you make accurate volume reading on a buret are
1. Leaving air bubbles buret tip or in the stopcock
2. Error due to parallax: Taking volume reading while looking at the scale of an inclined buret. Looking down the buret gives it an appearance of a higher reading than actual reading while up towards the meniscus will make it look lower than the actual value
3. Pouring in the liquid too rapidly into the buret forming droplets on the inner walls of the buret which can alter the volume reading of the buret when the drops settle into the remaining liquid in the buret
A practice that will not help you make an accurate volume reading is a. Make sure that the meniscus starts exactly at 0.00 mL.
When reading a burette at the beginning of a titration, you do not need the meniscus to start exactly at 0.00ml.
All you need is:
In conclusion, the meniscus starting at 0.00 ml is irrelevant and will not contribute much to an accurate reading.

Options for this question include:
a. Make sure that the meniscus starts exactly at 0.00 mL.
b. Make sure the meniscus falls within the marked range on the burette.
c. Read the volume with the meniscus at eye level.
d. Read the volume at the bottom of the meniscus.
