Group 17 elements are called the halogens . As they have seven valence electrons,they form salts with metals. As the molecules of  Group 17 elements absorb in visible regions these group elements are colored. They tend to form anions in ionic compounds. Hence option D is the correct answer.

Option (A) is incorrect because it incorrectly states that the Group 17 elements have a low electron affinity. Hence option A is incorrect.

Option (B) is incorrect because it incorrectly states that the Group 17 elements tend to form cations in ionic compounds. Hence option B is incorrect.

Option (C) is incorrect because it incorrectly states that both the Group 17 elements have a low boiling point. Hence option C is incorrect.
