**Core Concept**
The underlying principle being tested is the prevention of dental malocclusion and its associated complications, which are often caused by prolonged habits such as finger sucking. This habit can lead to the displacement of permanent teeth, affecting the alignment and positioning of the dental arches.

**Why the Correct Answer is Right**
Finger sucking can cause the upper front teeth to protrude and the lower front teeth to be pushed backward, leading to an overbite and other dental abnormalities. The American Academy of Pediatric Dentistry recommends that finger sucking habits be terminated by the age of 3 years to prevent these complications. This involves a combination of behavioral and habit-breaking strategies, such as using a pacifier with a built-in clip to discourage sucking.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to the prevention of finger sucking and its consequences on dental health.
**Option B:** This option is incorrect as it does not provide a clear plan for habit-breaking and may not be effective in preventing dental malocclusion.
**Option C:** This option is not a recommended method for terminating finger sucking habits and may not be effective in preventing dental malocclusion.

**Clinical Pearl / High-Yield Fact**
It is essential to address finger sucking habits early on, ideally by the age of 3 years, to prevent dental malocclusion and its associated complications. This can be achieved through a combination of behavioral and habit-breaking strategies, such as using a pacifier with a built-in clip or a mouthguard.

**Correct Answer:** C.
