PLEASE HELP ME Which of the following statements is true?

Geographic isolation is the main cause of speciation.
Hybrid organisms always produce sterile offspring.
If a population is spread out over too large area, they may become extinct.
Speciation can only happen when a population has very low genetic diversity.
