Concept:Identify which phrase from column (1) grammatically and contextually connects with a phrase from column (2) to form a meaningful sentence.
Explanation:Check each possible pair:
B‑D: “They haven't produced any credible” + “evidence for convicting him.”
This forms a logical sentence about lack of convincing proof.
C‑F: “The training aeroplane” + “has dual controls.”
This is correct as both parts refer to an aircraft’s features.
A‑F: “The change happens has dual controls” – does not make sense.
C‑D: “The training aeroplane evidence for convicting him” – illogical.
B‑E: “They haven't produced any credible response from him.” – “produce a response” is unnatural and less idiomatic; not the best fit.
Only two correct combinations exist: B‑D and C‑F.
Option A lists both these pairs.
Answer:Option A (B‑D and C‑F)
