In light of the above statements, choose the most appropriate answer from the options given below.
Show Hint
Because tall coconuts are outbreeders, they show high genetic heterozygosity and variation in the field.
Dwarf coconuts, being inbreeders, are highly homozygous and produce uniform offspring, making them useful parents for producing high-yielding $T \times D$ or $D \times T$ hybrids.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
This question focuses on the botanical classification and breeding systems of the coconut palm (*Cocos nucifera*).
Coconuts are broadly classified into Tall and Dwarf cultivars, which differ in their morphology, growth rate, and reproductive biology.
Step 2: Detailed Explanation:
Let us analyze each statement:
Statement (I): "The tall coconut cultivars are referred as var. typica, while dwarf type as var. Nana"
This statement is correct.
In botanical taxonomy, tall coconut cultivars (which are slow-growing, long-lived, and produce large nuts) are classified under the variety *typica* (*Cocos nucifera* var. *typica*).
The dwarf cultivars (which are fast-growing, shorter-lived, and produce smaller, colorful nuts) are classified under the variety *nana* (*Cocos nucifera* var. *nana*).
Statement (II): "Tall cultivars are the resultant of out breeding while dwarf are the resultant of inbreeding"
This statement is correct.
Tall coconut palms are highly cross-pollinated (outbreeding) because they exhibit protandry (the male flowers open and shed pollen before the female flowers on the same spadix become receptive).
This prevents self-pollination.
In contrast, dwarf coconut palms are highly self-pollinated (inbreeding) because their male and female flowering phases overlap closely on the same inflorescence, allowing for natural selfing.
Step 3: Final Answer:
Both Statement (I) and Statement (II) are correct.
This corresponds to Option (A).
