Answer : The correct answer is Ba²⁺ and Cl⁻ ions .

This can be explained using Solubility concept .

Solubility is defined as property referring to ability of a substance , SOLUTE , to dissolves in a SOLVENT . It is measured at maximum amount of solute that dissolves in solvent as equilibrium .

Solubility of any compound can be checked using Solubility Rule ( Image ).

BaCl₂ is salt of Chloride . Since the solubility rules says that salts if chlorides are soluble , Hence BaCl₂ is also soluble .

SO when BaCl₂ forms in aqueous solution , it again dissociates to forms ions since it is soluble in aqueous solution . It produced one Ba²⁺ ion and two ions of Cl⁻ .

The BaCl₂ dissociates as follows :

$BaCl_2 (aq) \rightarrow Ba^2^+ (aq) + 2 Cl^- (aq)$

Hence even BaCl₂ forms but it remain as dissociated ionic form as Ba²⁺ and Cl⁻ ions.

The answer to your question really depends on three things: how much water you have, how cold it is to start out, and how cold the things around it are. water actually freezes when it gets to 32 degrees fahrenheit (0 degrees celsius), but the time it takes to get there may be different. let's start with the first. if you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but i recommend using plastic cups and not glass ones). now let's move on to the second part. let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink. if you put both of them in the freezer, the one that started out colder will freeze first. for the third part, let's imagine that you have two glasses with the same amount of water in them, and the water is at the same temperature. imagine putting one outside on a really really cold day in georgia, and having a friend in alaska put one outside on the same day. since it would be so much colder in alaska, the glass of water there would freeze before yours. so, if you took a tiny bit of really cold water in a glass, and put it outside on a cold day in alaska, it would freeze a lot faster than a big glass of hot water outside on a cold day in georgia.
