Explanation:

- Throes: This word often refers to intense or violent pain and struggle, particularly in difficult situations or transitions such as childbirth or death.

- Option 1: Great pleasures

- Not relevant. The term throes conveys suffering or extreme discomfort, not joy or pleasure.

- Option 2: Deep sorrow

- While sorrow suggests sadness, throes indicate more of a physical struggle or pain, rather than emotional grief alone.

- Option 3: Severe pain

- Correct choice. Throes best align with the experience of severe or intense pain.

- Option 4: High disturbance

- Disturbance implies disruption or disorder, but lacks the specific focus on pain or struggle central to throes.
