Final answer:
The unit breakdown commonly required to be considered at each grade level in a college is 30 units for freshmen, 60 units for sophomores, 90 units for juniors, and 120 units for seniors. Option B is the correct choice, reflecting these academic standards.
Step-by-step explanation:
To determine the unit breakdown needed to be considered at each grade level in college, we typically refer to the credit system used by most institutions of higher education. The most common system involves earning a certain number of credit units or credits through course completion. Each course usually offers a set number of credits, which are accumulated as students progress through their education. Based on the information provided and common academic standards:
- Freshmen are typically students who have earned up to 30 units.
- Sophomores are students who have earned 30 to 59 units.
- Juniors are students who have earned 60 to 89 units.
- Seniors are students who have earned 90 units or more.
Therefore, the correct option that reflects these common standards is B) 30 units for Freshmen, 60 units for Sophomores, 90 units for Juniors, and 120 units for Seniors.
This unit classification system helps to ensure that students are on track for graduation within the traditional four-year timeline. However, these unit requirements can differ by institution, so it's always important to refer to your specific college or university's catalogue or academic policies for the most accurate information.
