B. A bond between two atoms: it doesn't matter if it's positive or negative or neutral, if there is a bond between two atoms, it is covalent.
Explanation:
Aldonic Acid:
Aldonic acids are suger acids.
General formula of aldonic acid = 
Aldonic acids are obtained by the oxidation of aldehydic group of suger.
So, aldonic acids have hydroxyl group at one terminal and carboxylic group at another terminal.
Gluconic acid is an example of aldonic acid.
Uronic Acid:
It is also a type of suger acid having carbonyl functional group at one terminal and carboxylic group at other terminal.
It is obtained by oxidation of hydroxyl group of the sugar.
Aldaric Acid:
Aldaric acid is also a type of sugar acid having carboxylic acid functional group at both the ends.
Both the hydroxyl group and aldehydic group are oxidized to form class of compound, called aldaric acid.

Answer:
A. NaHCO₃
Explanation:
NaHCO₃ ⇒ NaOH + H₂CO₃
NaOH is a strong base and H₂CO₃ is a weak acid. Therefore, NaHCO₃ is a salt of a strong base-weak acid reaction. The salt is basic because carbonic acid (H₂CO₃) is a weak acid so it remains undissociated. So, there is a presence of additional OH⁻ ions that makes the solution basic.
Hope that helps.
