Answer : Option D) Sodium Chloride.
Explanation : Boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure surrounding the liquid.
On the basis of bonding, the compound which has highest boiling point is sodium chloride.
Alcohol are found to have boiling point approximately as 78.37 °C.
Glucose usually melts at 146 °C.
Water boils at 100°C.
Sodium chloride has boiling point 1413 °C.
So, it is easy to identify that NaCl (sodium chloride) has highest boiling point amongst the given choices.

Answer:
0.432 drinks are toxic
Explanation:
The toxic dose of ethylene glycol is 0.1 mL per kg body weight (mL/kg). In grams (Density ethylene glycol = 1.11g/mL):
1.11g/mL * (0.1mL / kg) = 0.111g/kg
If the victim weighs 85kg, its letal dose is:
85kg * (0.111g/kg) = 9.435g of ethylene glycol
Using the concentration of ethylene glycol in the liquid:
9.435g of ethylene glycol * (550g liquid / 120g ethylene glycol) = 43.2g of liquid are toxic.
The drinks are:
43.2g of liquid * (1 drink / 100 g) =
<h3>0.432 drinks are toxic</h3>
