Question Analysis
This question tests the understanding of marginal relative frequency, which is the proportion of a single variable category (in this case, 11th-grade students) within the total population. The key is to correctly divide the marginal frequency by the total number of students.

Key Concept Explanation
Marginal relative frequency is obtained by dividing a marginal frequency (the number of students in a specific category) by the total number of the population. It reflects the proportion of a single variable category in the overall population and is usually presented as a decimal or percentage.

Step-by-step Solution
1. Identify the marginal frequency of 11th-grade students: 60
2. Identify the total number of students: 200
3. Calculate the marginal relative frequency:
