Which of the following is true about Tube Modules?

Tube modules are specialized containers used for transporting gases, and they resemble tube trailers in their design and functionality. Tube trailers are typically long, cylindrical tanks that are used to carry compressed gases, not solid masses or liquids. Tube modules, designed for safe transport, can often have several tubes bundled together, which makes them efficient for conveying gaseous substances.

The other statements are misleading. They do not transport solid masses, nor are they restricted to carrying only nitrogen; they can be used for several gases. Additionally, they are not exclusively for organic solvents, as they are compatible with a variety of gases. Thus, the comparison to tube trailers accurately represents the characteristics and uses of tube modules.
