Answer:
C. Pilate.
Step-by-step explanation:
The modern World English Bible translates the passage as:
65: Pilate said to them, "You have a guard. Go, make it as secure as you can."
66: So they went with the guard and made the tomb secure, sealing the stone.
The New International Version reads:
65: “Take a guard,” Pilate answered. “Go, make the tomb as secure as you know how.”
66: So they went and made the tomb secure by putting a seal on the stone and posting the guard.
