Actually Welcome to the Concept of the Lens and Ray Optics.
We must understand the Concept that,
1.) When a beam of parallel light pass through a Convex lens, all the rays get deviated and converges to a special point at the axis that is a Focus.
2.) When a beam of light passes through the Concave lens,the light beams diverge from one another forming a virtual focus in the primary side of lens,
Hence the above given diagram beam rays are diverging, it is a CONCAVE LENS
answer is C.) Concave lens
C. reducing the amount of garbage
Explanation:
The biggest long-term benefit of building a city's recycling building is that it helps to reduce that amount of garbage.
Recycling is simply the collection and processing of waste materials into new products that can be used again.
- Waste recycling helps to reduce that actual proportion and percentage of materials to be considered waste.
- The overall long term goal of any recycling procedure is to reduce the amount of garbage in the environment.

PV = nRT —> P = nRT/V
n = 0.250 moles of gas
R = 0.08206 L atm / mol K
T = 18 + 273 = 291 K
V = 7.50 L
P = (0.250)(0.08206)(291)/(7.50) = 7.96 atm
