Select the most appropriate option that can rectify the highlighted segment in the given sentence. If there is no need to rectify it, select ‘no rectification needed’.
I used a variety of sources to find the more cheap flight.

Correct option is C

The correct rectification of the highlighted segment is (c) cheapest.
· The phrase "the more cheap flight" is grammatically incorrect when comparing among multiple options. The correct superlative form of "cheap" is "cheapest," used here to indicate the lowest priced option among several.
· Grammatical rule used: Superlative adjectives are used to describe an object which is at the upper or lower limit of a quality (the tallest, the smallest, the fastest, the highest). They are used in sentences where a subject is compared to a group of objects. In this case, "cheapest" correctly modifies "flight" to express that it is the least expensive compared to all others considered.
· Example: Among all the options available, he chose the cheapest flight to save money.
