Reacting 1-chloro-2-ethylcyclohexene with hydrogen gas using a platinum catalyst would give a product of 1-chloro-2-ethylcyclohexane.
Hydrogen gas is a reducing agent, which in this reaction, simply mean that the alkene double bond in the cyclohexene will disappear because one of the two bonds forming the double bond (in the alkene) will be connected to a hydrogen atom. The platinum catalyst is necessary to allow the reaction to proceed at a much lower (activation) energy than would have been required.
The correct option is B.
After sorting the drugs into two groups, it is very important to check with the client, who is the one using the drugs, in order to ensure that the drugs have been properly sorted and no mistake was made. After ensuring that the drug has been accurately sorted then the ones that the client is no longer using can be put away in an appropriate safe location in order to avoid mix up.

The second reaction with the volume of 5L will occur faster as compared to the first reaction of volume 10L.
Volume is inversely proportional to the rate of reaction.
As volume increases rate of reaction decreases and as volume decreases rate of reaction increases.
Let's consider a reaction A → B.
r is rate of reaction and K is rate constant, A is the concentration of reaction.
r = k(A)
r is directly proportional to the A.
But the concentration of A is in Moles/liters (i.e. moles per unit volume)
r is inversely proportional to the volume of vessel or chamber.
Hence as volume increases rate of reaction decreases.

PV = nRT (where P = pressure; V = volume; n = number of moles; R = gas constant; T = Temperature)
Moles of He = mass of He ÷ molar mass of He = 10 g ÷ 4 g/mol = 2.5 mol
Now, based on the formula above P = (nRT) ÷ V
P = (2.5 mol × (0.082 L · atm/mol · K) × 233 K) ÷ 73 L ≈ 0.65 atm
