Indian National Congress agreed to end the Civil Disobedience Movement.

The correct answer is Option (4) → Indian National Congress agreed to end the Civil Disobedience Movement.

Out of the options you listed, only Indian National Congress agreed to end the Civil Disobedience Movement was an actual outcome of the Gandhi-Irwin Pact of 1931.

Here's a breakdown of the other options:

• Bhagat Singh, Rajguru and Sukhdev were to be given a fair trial: The Gandhi-Irwin Pact did not address the specific cases of individual revolutionaries like Bhagat Singh. Their trial and execution proceeded as planned.
• Indian provincial elections were announced: There's no direct link between the Pact and immediate announcement of elections. However, provincial elections were held later in the 1930s.
• Indian National Congress agreed on a peaceful partition of Bengal: The partition of Bengal was a separate event that happened in 1905 and later reversed in 1911. The Gandhi-Irwin Pact did not involve any agreement on Bengal's partition.
