What would be the data type of variable data in following statements ?

1. data = f.read()
2. data = f.read(10)
3. data = f.readline()
4. data = f.readlines()

1. data = f.read() — Variable data will be string data type.
2. data = f.read(10) — Variable data will be string data type.
3. data = f.readline() — Variable data will be string data type.
4. data = f.readlines() — Variable data will be list data type.
