Which of these best describes how an appropriate star chart is selected to locate objects in the sky?

match the temperature and humidity of the air
match the day and time of the year and location
match the latitude and number of stars in the sky
match the hemisphere and shape of constallations

The layout of the stars in the sky is determined by the date, time of night, and your location (mainly latitude). So to pick the best star chart, you should go with the one that's closest to the present date and your location, then make allowance for what time it is. Everything in the sky moves about a degree every 4 minutes.
