Which heading is more appropriate to assign to the above passage ?

A passage's heading must name the single issue or event that every paragraph's details serve to illustrate — not a source cited once, not a single reactive detail, and not merely the venue of one incident within a larger episode. The right title is broad enough to cover the whole account, yet no broader than the passage actually supports.

The passage traces the shift in British policy that followed the decision to hold public trials of Indian National Army (I.N.A.) prisoners: it opens with that decision, moves to the first trial at the Red Fort with its Hindu, Muslim and Sikh defendants, records the defence counsel and the country-wide protest the trial provoked (including the Muslim League), cites an Intelligence Bureau note and a journalist's report on the communal mood among the accused, and closes with the British government's fear that I.N.A. sympathy would spread to the Indian Army. Every one of these details — the decision, the trial, the protest, the press and intelligence commentary, and the army anxiety — is an aspect of the same underlying event: the prosecution of the I.N.A. prisoners.

• Wavell's Journal names only the source the passage cites once, for the phrase 'the edge of a volcano' — a citation, not the event the passage narrates.

• Role of Muslim League names one reaction the passage records among several — it does not cover the initial British decision, the trial itself, or the government's army-loyalty concern.

• Red Fort Prisoners names only the venue and defendants of the first trial — the passage's account extends beyond that one trial to the wider policy toward all the detained I.N.A. personnel and its national and military fallout.

Because the passage's narrative — the decision to prosecute, the Red Fort trial, the protest it drew, and its feared spread to the army — is entirely an account of the I.N.A. prisoners' prosecution, 'I.N.A. Trials' is the heading that spans the whole passage.
