Concept:The need to replace Judas Iscariot was based on the fulfillment of Old Testament prophecy.
Explanation:After Judas betrayed Jesus, the apostles met to choose his successor.
Peter stood up among the believers and explained the situation.
He referenced the Psalms to show that Judas's betrayal and replacement were foretold in Scripture.
Peter quoted Acts 1:16: "the scripture had to be fulfilled."
He also cited Acts 1:20, where the Psalms say: "His office let another take."
Therefore, the reason for the replacement was not the timing of Judas's death or the symbolic number of the twelve.
The primary reason was that the written prophecy had to be fulfilled.
Option A is incorrect because the Bible does not give that reason.
Option B is incorrect because the text does not mention preserving a status quo.
Option D is incorrect because the disciples are not linked to the twelve tribes here.
Answer:C. prophecies of the scripture needed to be fulfilled.
