This question appear incomplete or has some wrong contents in it. Strontium, fluorine and oxygen do not exist in the same compound. This can even be better confirmed by the options provided. The options provided just two compounds that are rightly named
Strontium fluoride - SrF₂
Strontium Chlorate - SrCl₂
The options strontium fluorate and strontium fluorine are wrong names of the option strontium fluoride. Thus, if the question was asking of a compound that has just strontium and fluorine, the answer would have been <u>strontium fluoride</u> (SrF₂)
