Which of the Following Points Suggests That the First Hydride

Which of the following points suggests that the first hydride in Groups 14-17 exhibit hydrogen bonding. Please select all that apply.

A) There is a steady increase in the boiling point of the hydrides from the second row onwards but the boiling point of the hydride for the first element in any group is anomalously high.
B) There is a steady increase in the melting point of the hydrides from the second row onwards but the boiling point of the hydride for the first element in any group is anomalously high.
C) There is a steady decrease in the boiling point of the hydrides from the second row onwards but the boiling point of the hydride for the first element in any group is anomalously high.
D) There is a steady decrease in the melting point of the hydrides from the second row onwards but the boiling point of the hydride for the first element in any group is anomalously high.
