Mitochondrial complex I is a large protein complex located in the inner mitochondrial membrane. During cellular respiration, this complex uses energy to transport hydrogen ions (

H^{+}

) against their concentration gradient. The steps of

H^{+}

transport carried out by mitochondrial complex I are depicted in the following diagram.

Given the concentration gradient established by mitochondrial complex I, which of the following movements can occur?

(Choice A)
$H^{+}$ ‍ can move into the mitochondrial matrix without a direct input of energy.
(Choice B)
$H^{+}$ ‍ can move into the intermembrane space by passive transport.
(Choice C)
$H^{+}$ ‍ can move into the intermembrane space without the help of a membrane protein.
(Choice D)
$H^{+}$ ‍ can move into the mitochondrial matrix by directly diffusing through the inner mitochondrial membrane.
