Answer: The correct answer is A.
Explanation: Concentration is defined as the moles of solute present in 1 liter of solution.
Mathematically,
Here, James has placed a solution of salt in water on a hot plate. By placing the solution on a hot plate, evaporation of water is occurring which results in the decreases of the volume of the solution. As this happens, the denominator of the fraction decreases, which results in the increase of concentration.
Hence, the correct option is A.

Answer: The major product of the reaction between Hydrobromic Acid and 2-bromo-1-butene in the presence of ether and acid is 2,2-dibromobutane.
Explanation:
The mechanism of the reaction is supported by the Markovnikov's rule which explains that in the addition reaction of alkenes by hydrogen-halogen compounds, the incoming halogen substituent goes to the more substituted Carbon. It can also be stated that incoming hydrogen atom goes to the Carbon with more Hydrogen atoms.
The only case when the reverse of Markovnikov's rule takes place is when Hydrogen peroxide is present and the addition reagent is HBr.
This case is not like that and it simply follows the Markovnikov's rule.
I'll add an attachment of the reaction to this now.
