Detailed Solution

Step 1: Identify the biological context

The question pertains to the anatomy of the nervous system in amphibians, specifically the frog (Rana tigrina), which is a standard model organism in the NEET biology syllabus.

Step 2: Recall cranial nerve classification

Cranial nerves are the nerves that emerge directly from the brain. In vertebrates, the number of cranial nerves varies across different classes. Humans possess 12 pairs, whereas amphibians like frogs possess a different count.

Step 3: Determine the count for frogs

Based on the anatomical study of the frog's brain, there are exactly 10 pairs of cranial nerves that arise from the brain. These include the olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, auditory, glossopharyngeal, and vagus nerves.

Final Answer: 10

Pedagogical Audit
Bloom's Analysis: This is an REMEMBER question because it requires the student to recall specific anatomical data points provided in the NCERT textbook regarding amphibian morphology.
Knowledge Dimension: FACTUAL
Justification: The question tests the student's knowledge of specific biological facts (number of cranial nerves) rather than the application of a complex process or theory.
Syllabus Audit: In the context of NEET, this is classified as KNOWLEDGE. This question is a direct retrieval task from the Structural Organization in Animals unit, which is a high-yield area for NEET examinations.
