The Makkan Surah with the main objective of reassuring the Prophet (SAW) at a time of distress is Surah ad-Duha. Surah ad-Duha is the 93rd chapter of the Qur'an and was revealed in the early days of the Prophet's mission in Makkah when he was feeling distressed and anxious. The Prophet had not received any revelations from Allah for a long time, and the disbelievers were mocking him and calling him a liar. In this Surah, Allah reassures the Prophet (SAW) that He has not forgotten him and that his efforts will not go to waste. Allah tells the Prophet that He has blessed him with many favors and will continue to do so. The Surah is a beautiful reminder to the Prophet that he is not alone and that Allah is always with him. Therefore, among the given options, Surah ad-Duha is the Makkan Surah with the main objective of reassuring the Prophet (SAW) at a time of distress.
