Here are the essential concepts you must grasp in order to answer the question correctly.
Carbon-13 NMR Spectroscopy
Carbon-13 NMR spectroscopy is a technique used to determine the structure of organic compounds by analyzing the magnetic environment of carbon atoms. Each unique carbon environment in a molecule produces a distinct signal in the spectrum, allowing chemists to infer structural details based on the number and position of these signals.

Chemical Equivalence
Chemical equivalence refers to the condition where atoms or groups in a molecule are indistinguishable in terms of their chemical environment. In ¹³C NMR, chemically equivalent carbon atoms produce a single signal, as they experience the same magnetic environment, simplifying the spectrum and aiding in structural analysis.

Symmetry in Molecules
Symmetry in molecules affects the number of signals observed in NMR spectroscopy. Symmetrical molecules often have fewer unique carbon environments due to equivalent positions, leading to fewer signals. Recognizing symmetry helps predict the number of signals and understand the molecular structure more efficiently.
