Given below are two statements:
Statement I: The halogen that makes longest bond with hydrogen in HX, has the smallest covalent radius in its group.
Statement II: A group 15 element's hydride \(EH_3\) has the lowest boiling point among corresponding hydrides of other group 15 elements. The maximum covalency of that element \(E\) is 4.
In the light of the above statements, choose the correct answer from the options given below.
