Answer:
C.
Step-by-step explanation:
Martin Perfecto de Cos served as a General in Mexican army during the Texas Revolution. During the Texas Revolution, Cos along with his 500 army men entered Texas states to arrest the rebels.
When Cos entered the San Antonio town, he along with his men was beseiged and kept for 56 days, after which Cos surrendered himself.
General Cos and his men were allowed to leave after signing a document, termed as 'Terms of Surrender'. The term that was not one of term written in agreement is in option C. Last 18th term of the document states that all the prisoners shall be set at liberty. Since the document was a surrender agreement consenting upon the freedom of General Cos and his army men, therefore, option C is not one of the terms.
Thus option C is correct.
