The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
We've got to have / beefed-up intelligence, / including much strong / human intelligence than before.

Correct option is C

Option (c) contains an error.
Error Explanation: The phrase “much strong” is grammatically incorrect because the word “strong” is a gradable adjective and should be preceded by “much stronger” when used in comparison.
· The correct comparative structure is “much + comparative adjective”, so it should be “much stronger”.
Grammatical rule used:
· When comparing degrees of adjectives, we use comparative forms such as “stronger,” “better,” etc.
· “Much” can modify a comparative adjective (e.g., much better, much stronger).
Correct sentence: including much stronger human intelligence than before.
Example:
· This laptop is much faster than my old one.
