Approximately twenty five elements A: occur naturally on earth B: are in the human body C: are in the periodic table of elements

OpenStudy (abhisar):

What do you think it should be?

OpenStudy (anonymous):

@Abhisar well I think its A but I'm not sure if I'm right

OpenStudy (abhisar):

Umm..that's incorrect. Have a look on periodic table. All the element before uranium i.e. At no. 92 are naturally occuring elements (Except Technetium and Promethium )

OpenStudy (anonymous):

@Abhisar ok thank you, yea I thought it was wrong

OpenStudy (abhisar):

And also there are more than 25 elements in periodic table which leaves us only one correct option.

OpenStudy (anonymous):

@Abhisar ok thank you
