**Core Concept**
The State Level Dispute Redressal Commission is a forum for resolving disputes related to consumer grievances, particularly in cases where the District Consumer Disputes Redressal Forum is unable to provide a satisfactory resolution. This commission is established under the Consumer Protection Act, 1986.

**Why the Correct Answer is Right**
The correct answer is related to the hierarchical structure of the consumer dispute redressal forums in India. The State Level Dispute Redressal Commission is the second-tier forum, which hears appeals against the orders of the District Consumer Disputes Redressal Forum. This commission has the power to pass orders that can be enforced by the civil courts.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the State Commission does not deal with complaints against unfair trade practices. That is the jurisdiction of the Central Consumer Protection Authority.
**Option B:** This option is incorrect because the National Consumer Disputes Redressal Commission (NCDRC) is the highest consumer court in India, which hears appeals against the orders of the State Commissions.

**Clinical Pearl / High-Yield Fact**
It's essential to know the hierarchy of consumer dispute redressal forums in India, as it can impact the jurisdiction and appealability of consumer cases.

**Correct Answer: C**. The State Level Dispute Redressal Commission is the correct answer.
