Explanation Option (a) is given as ‘consuming extra salt’. As mentioned earlier, osmosis plays a crucial role in maintaining the water level in our body. This is further dependent on sodium and potassium levels. So, any altercations in these levels will alter the water content in our body. Consuming extra salt will raise the amount of sodium in our bloodstream as common salt is sodium chloride. This will further reduce the ability of kidneys to remove the water and hence water level will increase and thus the blood pressure. So, it is the correct answer. Option (b) is given as ‘consume extra sugar’, which is incorrect, as consuming more sugar will increase the sugar levels in the blood, it would lead to water loss...

Water balance in our body is maintained by the kidneys or by the brain. Both of these contain specialized osmoreceptors that detect any change in plasma osmolarity. Kidneys play a crucial role in drawing extra water from the body through the process of osmosis. Osmosis is regulated by levels of sodium and potassium in the blood and any altercation in these levels will either increase or decrease the blood pressure.
