What’s the best way to rewrite the round about expressions for the period of two weeks? for the period of at least two weeks, for weeks, for two weeks , for the period of a half month

C - for two weeks

Option C (for two weeks) is the most clear of the options. At least two weeks could be 3 or more weeks, for weeks is vague and indeterminate and the period for half a month is confusing.
