Here are the essential concepts you must grasp in order to answer the question correctly.
NMR Spectroscopy
Nuclear Magnetic Resonance (NMR) Spectroscopy is a technique used to determine the structure of organic compounds by observing the magnetic properties of certain atomic nuclei. In NMR, the splitting pattern of hydrogen signals provides information about the number of neighboring hydrogen atoms, which helps in deducing the molecular structure.

Spin-Spin Coupling
Spin-spin coupling, also known as J-coupling, occurs when the magnetic field of one nucleus affects the magnetic field of a neighboring nucleus. This interaction causes the splitting of NMR signals into multiplets, with the number of peaks in a multiplet indicating the number of adjacent hydrogens plus one (n+1 rule).

Chemical Shift
Chemical shift in NMR refers to the resonant frequency of a nucleus relative to a standard in a magnetic field. It provides information about the electronic environment surrounding the nucleus. Different chemical environments cause shifts in the resonance frequency, allowing for the identification of different types of hydrogen atoms in a molecule.
