Correct answer is magnesium bromide. This is an ionic compound with metal forming a positive ion - K+ and halogen forming a negative ion - Br-. When group 7 element form ions they have a suffix -ide. Bromine is the element and when it forms a negative ion bromine is called bromide with the suffix.

Explanation:
It is clear from various studies that the Earth has had a diverse geologic history in which events like drastic climate changes, upsurging of oceans, rapid desertification, etc., have taken place many times.
Thus, the possibility of an ocean and forest having shared a single location at different times in the history of Earth cannot be neglected.
