Identify product \( A' \) in the reaction shown below:

In the given reaction, the acylation of the amine group takes place, followed by nucleophilic substitution. The reaction is expected to lead to the formation of a **brominated amide**. This matches with the product in **option (b)**. Therefore, the correct answer is **option (b)**.

The correct increasing order of basic strength of amine is:
(A) C₆H₅NH₂ < NH₃ < C₆H₅CH₂NH₂ < C₂H₅NH₂ < (C₂H₅)₂NH
(B) NH₃ < C₆H₅NH₂ < C₆H₅CH₂NH₂ < C₂H₅NH₂ < (C₂H₅)₂NH
(C) C₆H₅CH₂NH₂ < C₆H₅NH₂ < NH₃ < C₂H₅NH₂ < (C₂H₅)₂NH
(D) C₂H₅NH₂ < (C₂H₅)₂NH < C₆H₅NH₂ < NH₃
(E) NH₃ < C₂H₅NH₂ < C₆H₅CH₂NH₂ < (C₂H₅)₂NH < C₆H₅NH₂
