Respuesta :
In 1720, colonist living in South Carolina petitioned England to build forts to their south.
Answer: The correct answer is "In the 1720s, colonists living in South Carolina petitioned England to build forts to their south".
Explanation: The last option is the correct one because it combines the four sentences provided into one sentence and does not include any grammar mistake. On the other hand, the first option ("In the 1720s, colonists who were living in South Carolina. Petitioned England, They wanted forts built to their south") fails to combine the four sentences into one and the second and third options present grammar mistakes: in both cases, the verb "petitioned" is not followed by an object. In contrast, the last option is free from grammar mistakes since the verb "petitioned" is followed by the preposition "to" and has an object ("to build forts to their south").
