Concept:The quotation is taken from the Makkan chapter that opens with Allah's oath by the fig and the olive.
Explanation:The words "best stature" translate the Arabic phrase
ahsani taqwim, which is the distinctive expression of this short chapter.
In the passage, Allah declares that He created man in the finest form, then reduced him to the lowest of the low, except those who believe and do good works.
This full statement is found in Surat At-Tin, which is Chapter 95 of the Qur'an, spanning verses 4, 5 and 6.
The phrase "created man of the best stature" belongs to verse 4, while the reduction and the exception appear in verses 5 and 6.
Surat al-Asr speaks about time and loss, Surat al-Alaq commands reading, and Surat al-Bayyinah discusses the clear proof, so none of them contains this quotation.
Answer:The correct option is C. al-Tin.
