Total number of students = 200

Number of students who like cold drinks = 140

Number of students who like milkshakes = 120

Number of students who like both cold drinks and milkshakes = 80

Number of students who like at least one of the drinks = (140 + 120) - 180

Number of students who like at least one of the drinks = 180

Hence, "180" is the correct answer.
