Annelids have neither an external or an internal shell. Examples of annelids are
earthworms and leeches.
Explanation:
In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.
Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.
Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.
Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.
Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.
- Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
- This leaves a partial negative charge on it.
- The other electron then becomes partially positively charged.
- We can then say, the more electronegative specie undergoes reduction.
- The less electronegative one undergoes oxidation.

According to the cephalocaudal trend, the head develops more rapidly during the prenatal period than the lower part of the body.
<h3>What is Cephalocaudal trend?</h3>
This refers to the pattern of growth during the prenatal stage in which the head grows more than the other parts of the body.
This is therefore the reason why option B was chosen as the most appropriate choice.
