(A) In the Battle of Roncevaux Pass in 778, the rearguard of the Frankish army, under the command of Roland, was obliterated due to an ambush by the Basque army, an event made famous in La Chanson de Roland
(B) In the Battle of Roncevaux Pass in 778, the Basque army ambushed the Frankish army, the rearguard of the Frankish army, under the command of Roland, was obliterated, and the event was made famous in La Chanson de Roland
(C) La Chanson de Roland made famous the obliteration, due to an ambush by the Basque army, of the rearguard of the Frankish army, under the command of Roland, at the Battle of Roncevaux Pass in 778
(D) In La Chanson de Roland, the Basque army ambushed the rearguard of the Frankish army, under the command of Roland, and obliterated them, and this event was famous at the Battle of Roncevaux Pass in 778
(E) In the Battle of Roncevaux Pass in 778, the rearguard of the Frankish army, under the command of Roland, ambushed and obliterated by the Basque army, an event made famous in La Chanson de Roland
B, D & E can be eliminated easily.
B- "the Basque army ambushed the Frankish army, the rearguard of the Frankish army, under the command of Roland" - the rearguard of the Frankish army is an appositive for Frankish army which is just plain wrong
D- The battle does not happen in the book "La Chanson de Roland". The book simple describes the battle
E- Not a complete sentence
The remaining choices are A & C.
In A, there is just 1 simple error which is the use of "due to". Simple rule: Due to is used for modifying a noun and because of is used for modifying a verb.
The only option left is C, which is the correct answer.
