Answer:
Both Options C and D are appropriate.
But I'd go with Option D since "Direct Air Capture" would eventually lead to "Ground Injection"
OPTION D.
<u>Answer:</u> The new volume of the gas is 0.11 L
<u>Explanation:</u>
To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.
The equation follows:

where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
At STP:
The temperature at this condition is taken as 273 K and the pressure at this condition is taken as 1 atm or 101.3 kPa.
We are given:

Putting values in above equation, we get:

Hence, the new volume of the gas is 0.11 L
Explanation:
The name alkyne which includes the letters "yne" means that there are three bonds attache to the carbon at the specified place. It is an unsaturated hydrocarbon because it contains a triple bond.
For example, 3-heptyne is a seven membered carbon chain with a triple bond at carbon 3.
The formula of 3-heptyne is as follows.
