Concept:The phrase “create up” is incorrect; the correct verb to describe the composition of a year is “make up”.Explanation:The sentence states that 365 days “create up” the number of days in a year.The verb “create” means to bring something new into existence, which does not fit here.We use “make up” to indicate that smaller parts form a whole.Therefore, part (b) should be “make up the number of days”.The corrected sentence is: Three hundred and sixty five make up the number of days in a calendar year.Answer:(b)
