To solve this exercise it is necessary to apply the concepts related to Robert Boyle's law where:
Where,
P = Pressure
V = Volume
T = Temperature
n = amount of substance
R = Ideal gas constant
We start by calculating the volume of inhaled O_2 for it:
Our values are given as
P = 1atm
T=293K 
Using the equation to find n, we have:
Number of molecules would be found through Avogadro number, then

Answer:d-All of the above
Explanation:
A resistor is a device used in electrical circuits that offers resistance to current flow.In automotive circuit commonly used resistor are
- Fixed value
- Stepped
- Variable
Fixed value:A fixed value electrical resistance is one whose value is resistance value is fixed and does not change in circuit.
Stepped resistance:Stepped resistor also called as tapped resistors provide two or more set resistor values. In a circuit, the various resistances are attached to different terminals. When the switch is shifted, different resistance values are put in the circuit.
Variable resistance:The variable resistor gives more control over the current flow by increasing the resistance. When the resistance of the variable resistor increases, the amount of current allowed to flow in the circuit decreases.
