**Core Concept**
The management of acute scrotum in a young boy involves distinguishing between testicular torsion and epididymitis, as timely intervention is crucial to preserve testicular function. Testicular torsion requires emergency surgical intervention to prevent ischemic damage.

**Why the Correct Answer is Right**
The correct answer is related to the management of testicular torsion. In cases of suspected testicular torsion, the patient should undergo immediate surgical exploration, regardless of the duration of symptoms. This is because ischemia can occur rapidly, leading to testicular necrosis. The key here is to recognize the clinical presentation of testicular torsion, which includes acute onset pain, swelling, and possibly a high-riding testis.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it implies that the management of testicular torsion can be delayed, which is not the case.
**Option B:** This option is incorrect as it suggests that epididymitis is the primary concern in the acute scrotum, when in fact testicular torsion is a more urgent condition.
**Option C:** This option is incorrect as it implies that ultrasound is the primary diagnostic tool for testicular torsion, when in fact clinical evaluation and surgical exploration are more critical.
**Option D:** This option is incorrect as it suggests that the management of testicular torsion does not require surgical intervention, which is not true.

**Clinical Pearl / High-Yield Fact**
Remember the "5 Ps" of testicular torsion: pain, palpable mass, positive Prehn's sign (pain worsens with elevation), possible testicular atrophy, and pulseless testis.

**Correct Answer:** A.
