Explanation

Magtymguly Faragi is the correct answer because the forum in Ashgabat in 2024 celebrated his 300th birth anniversary. Omar Khayyam is incorrect as he is a Persian poet whose celebration is not linked to this event. Allama Iqbal is incorrect because he is associated with Pakistan and not this specific Turkmen commemoration. Ferdowsi is incorrect because he is a famous Persian writer, not the subject of this particular anniversary.
