Answer:
Conjugate base of chloroacetic acid will be weakest.
Explanation:
of an acid is a parameter to predict it's acidic strength.
Higher the , higher will be acid dissociation . Hence acidity will be higher.
We know that the stronger an acid, the weaker it's conjugate base. So higher the value of an acid, weaker will be it's conjugate base.
The order of value: 
So, conjugate base of chloroacetic acid will be weakest.
I think it would be D because it makes the most sense
Answer: metal
Explanation: it says element so conductor and semiconductor are out and a halogen is a group of gases on the periodic table so this brings up to a conclusion of metal.
