Correct Answer: Eliminating Immediate Left Recursion (A \rightarrow A\alpha / \beta)

To remove immediate left recursion of the form
$A \rightarrow A\alpha \mid \beta$
(where (\beta) does not start with (A)), the standard transformation introduces a new nonterminal (A') and rewrites the grammar as:
$A \rightarrow \beta A'$
$A' \rightarrow \alpha A' \mid \epsilon$

This directly matches option (i).

Therefore, the correct choice is (i) (A \rightarrow \beta A').
