Answer is: D. Cl (chlorine).
The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).
Barium, potassium and arsenic are metals (easily lost valence electrons), chlorine is nonmetal (easily gain electrons).
Alkaline metals (in this example, potassium) have lowest ionizations energy and easy remove valence electrons (one electron), earth alkaline metals (in this example, barium) have higher ionization energy than alkaline metals, because they have two valence electrons.
Nonmetals (in this example chlorine) are far right in the main group and they have highest ionization energy, because they have many valence electrons.

Answer:
The body temperature would rise by 47.85 °C
The amount of water the body evaporates is 4.15 kg.
This makes sense because firstly the value obtained is positive then secondly it is a normal occurrence in the real world that in a place where the temperature is high the body usually produce sweat in order to balance its internal temperature
Explanation:
Considering the relationship (between the heat released and the mass of the object) as shown below
q = msΔT
where q is the heat released per day =
m is the mass of the body = 50 kg
ΔT is the temperature rise = ?
s is the specific heat of water = 
substituting values we have
=
ΔT
ΔT =
= 47.85°C
To maintain the normal body temperature (98.6F = 37°C) the amount of heat released by metabolism activity must be utilized for evaporation of some amount of water
Hence

Note (1 kg = 1000 g)
This makes sense because firstly the value obtained is positive then secondly it is a normal occurrence in the real world that in a place where the temperature is high the body usually produce sweat in order to balance its internal temperature
