Answer:
a. True
Explanation:
Using Complete Jewish Bible CJB, the only one quote from the Old Testament in the Gospel or Book of Mark is in MARK (CJB) 12:26 which stated that"...the God of Avraham, the God of Yitz’chak and the God of Ya‘akov’" this quote can, however, be found in the Old Testament in Exodus 3:6 (CJB) which stated, "... the God of Avraham, the God of Yitz’chak and the God of Ya‘akov.”
Also, it is True that there is a marked absence of references to the law of Moses in the Gospel of Mark.
