Explanation:

Identify the question and options

The question asks: "Which of the following cranial nerves is mispaired?"
The options shown in the image are:

• Facial - VII
• Optic - I
• Accessory - XI
• Abducens - VI
• Trochlear - IV

Analyze each pairing

• Facial nerve is Cranial Nerve VII (CN VII). This is paired correctly.
• Optic nerve is Cranial Nerve II (CN II). Cranial Nerve I (CN I) is the olfactory nerve. Therefore, "Optic - I" is mispaired.
• Accessory nerve is Cranial Nerve XI (CN XI). This is paired correctly.
• Abducens nerve is Cranial Nerve VI (CN VI). This is paired correctly.
• Trochlear nerve is Cranial Nerve IV (CN IV). This is paired correctly.

Determine the correct choice

The mispaired option is "Optic - I" because the optic nerve is CN II, while CN I is the olfactory nerve.

Answer:

• Facial - VII
• Optic - I (Correct answer)
• Accessory - XI
• Abducens - VI
• Trochlear - IV
