Concept:Adverb placement in English sentences – the adverb 'never' should be placed between the auxiliary verb and the main verb.
Explanation:The sentence contains three underlined parts: (a), (b), and (c).
Part (c) reads: "and never you will get it back".
The word 'never' is an adverb, and its correct position in a clause with an auxiliary verb like 'will' is after the auxiliary verb.
The proper order is: subject + auxiliary verb + adverb + main verb.
Therefore, "never you will" is incorrect; it should be "you will never".
This reversal of word order in part (c) makes it grammatically faulty.
No errors exist in parts (a) or (b).
Thus, the error is only in part (c).
Answer:(c)
