In a way, all of the answers could be argued for (for example: in the first option: if the scientists' opinions are understood to be "informed understanding of the causes of events"), but one of the options is the best:
Scientific laws describe specific relationships in nature without offering
an explanation.
The reason why I think this is true is that many laws are phased too short and too concise to provide comprehensive explanations, instead they describe the relationships that must hold.
One of the options is pplain false:
Scientific laws explain why natural events occur. -"Scientific laws were theories that have been tested, proven, and adopted as laws." - since they are not adopted as laws.
Answer:
Groups like the Halogens, which include Chlorine and Flourine, share similar properties both behaviorally and structurally. The Periodic Table is essentially a bunch of patterns and trends and the groups (like the one with Sodium and Potassium) were grouped together because of these similarities.
Explanation:

Ammonia is a base, and sulfuric acid is well, an acid. When an acid and base react, they form a salt. In the case of ammonia and sulfuric acid, they will react to form ammonium sulphate.
It is a solid and will dissolve in water. One would then need to separate it from the sulfuric acid that remains and then treat it with sodium hydroxide to get ammonia again.But you will likely use aqueous sodium hydroxide, which means that you have to find a way to dry the product as a result. Back to square one.

Answer: Crystals differ in physical properties, i.e., in hardness, cleavage, optical properties, heat conductivity, and electrical conductivity.
These properties are important since they sometimes determine the use to which the crystals are put in industry.
