A) 1.0-1.5 ppm
B) 2.0-3.0 ppm
C) 4.5-5.5 ppm
D) 7.0-8.0 ppm
E) 9.0-10.0 ppm
Proton NMR
A spectroscopic technique used to determine the structure of organic compounds by analyzing the environment of hydrogen atoms.
Aromatic Ring
A cyclic, planar molecule with delocalized π electrons over the atoms forming the ring, following Huckel's rule.

Final Answer :
D
Explanation :
Hydrogens bound to the aromatic ring typically appear in the region of 7.0-8.0 ppm in the proton NMR spectrum. This is known as the aromatic region and is characterized by a group of intense and sharp peaks.
