**Core Concept**
The detection of mutations is crucial in molecular diagnostics, particularly in genetic disorders. Various techniques are employed to identify mutations, including PCR-based methods, sequencing, and hybridization techniques.

**Why the Correct Answer is Right**
The correct answer is related to the detection of mutations, which involves identifying changes in the DNA sequence. Techniques like PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism), sequencing (Sanger sequencing or Next-Generation Sequencing), and hybridization techniques (such as Southern blotting or Northern blotting) are commonly used for mutation detection.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not relevant to mutation detection.
**Option B:** This option is incorrect as it is more related to identifying copy number variations.
**Option C:** This option is not directly related to mutation detection; it's more related to measuring gene expression levels.

**Clinical Pearl / High-Yield Fact**
In molecular diagnostics, the choice of technique for mutation detection depends on the type of mutation, the location of the mutation, and the availability of resources.

**Correct Answer: B. This option is incorrect as it is more related to identifying copy number variations.**
