Nested List comprehension

I have 2 lists, A and B.

• A is list of dictionaries which contain list of values.
• B is a simple list.

Requirement is to add the elements of list B into dictionary values of A.

Below is the code,

a = [{'a':[1,5]}, {'b' : [6,10]}, {'c' : [11,15]}]
b = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]

for i in a:
  for k,j in i.items():
      for m,n in enumerate(b):
          if j[0]<= n<=j[1]:
              j.append(n)

print(a)

[{'a':[1,5,1,2,3,4,5]}, {'b' : [6,10,6,7,8,9,10]}, {'c' : 
[11,15,11,12,13,14,15]}]

# tried list comprehension
a= [{k:n} for i in a for k,j in i.items() for m,n in enumerate(b)
if j[0]<= n<=j[1]]

print(a)

[{'a': 1}, {'a': 2}, {'a': 3}, {'a': 4}, {'a': 5}, {'b': 6}, {'b': 7}, 
{'b': 8}, {'b': 9}, {'b': 10}, {'c': 11}, {'c': 12}, {'c': 13}, {'c': 
14}, {'c': 15}]

Question is whether this can be done using list comprehension? I have tried but unable to generate the required output.
