Answer:
The correct option is, C "Confiderate officers"
Explanation:
The Army of the Confederate States of America (Army of the Confederate States of America - ACSA - in English) was organized on March 6, 1861 to defend the newly created Confederate States of America from the military actions of the government of the States United during the American Civil War.
At most, I estimate that 1.4 million men fought in the Confederate Army during the war. Although he won a significant number of battles (especially in the theater of eastern operations, under General Robert E. Lee), the lack of centralized control of the Army and logistics and the advantage of the United States workforce condemned the Confederate States and their army to defeat in April 1865
The participle in this sentence is D. Singing. Participles are formed by turning a verb into an adjective to modify another word. Therefore, singing here is a verb and is also modifying the word group.
it is appropriate to break the rule that requires subjects joined by and to use a plural verb when either and neither are subjects. They always take singular verb.
For example :
