Solution:The archaeological sites that do not have an early Harappan level among the options given are Lothal and Desalpur. Lothal, primarily known for its mature Harappan phase features such as a sophisticated dockyard and advanced urban planning, does not have significant evidence of the early Harappan level.
Similarly, Desalpur, while less frequently discussed in the context of the major Harappan sites, also lacks clear evidence of early Harappan occupation. This sets these sites apart from others like Kot Diji, which is famous for its early Harappan fortifications and related cultural layers.
