(a) It can not be adulterated
(b) It takes less time to fill the fuel tank
(c) It burns more efficiently
(d) It is cheaper
(e) It is less inflammable.
Choose the most appropriate answer from the options given below
(1) (a), (b), (c), (e) only
(2) (a), (c), (d) only
(3) (a), (b), (d), (e) only
(4) (c), (d), (e) only
Answer: Option (2)
Explanation:
Compressed Natural Gas is considered a better fuel than diesel due to several advantages related to efficiency, cost, and environmental impact.
CNG cannot be adulterated easily because it is supplied in sealed cylinders,
making statement (a) correct.
CNG burns more efficiently than diesel and produces fewer harmful emissions such as carbon monoxide and particulate matter,
so statement (c) is correct.
CNG is generally cheaper than diesel, which reduces fuel cost for vehicles,
hence statement (d) is correct.
CNG does not take less time to fill the fuel tank compared to liquid fuels,
so statement (b) is incorrect.
CNG is highly inflammable, although it disperses quickly when leaked,
making statement (e) incorrect.
Therefore, the correct set of statements is
(a), (c), and (d), corresponding to option (2).
