Answer:
I would say ether the first one or the third one because on those questions you always want to choose the one that gives the most information or sound more believe
Hope this helped
The binding energy of the electrons (also known as the work function of the surface) is determined as 2.43 x 10⁻¹⁹ J.
<h3>Binding energy of the electrons</h3>
The binding energy of the electrons is also known as work function of the metal and it is calculated as follows;
Ф = E - K.E
where;
Ф = hf - 86.2 kJ/mol
Ф = hc/λ - 86.2 kJ/mol
Ф = (6.63 x 10⁻³⁴ x 3 x 10⁸ )/515 x 10⁻⁹ - 86.2 kJ/mol
Ф = 3.86 x 10⁻¹⁹ J - (86200 J/mol)/(6.02 x 10²³)
Ф = 3.86 x 10⁻¹⁹ J - 1.43 x 10⁻¹⁹ J
Ф = 2.43 x 10⁻¹⁹ J

The most important reaction involved in the reoxidation of NADH is Pyruvate → lactate
Two ATP were generated as a net result of glycolysis, two NAD+ were converted to two NADH + H+, and two glucose molecules were divided into two pyruvate molecules.
Pyruvate will go through a process called fermentation when oxygen is absent.
The NADH + H+ from glycolysis will be recycled back to NAD+ during fermentation, allowing glycolysis to proceed.
NAD+ is converted during the glycolysis process into NADH + H+.
Glycolysis cannot proceed without the presence of NAD+.
The NADH produced during glycolysis will be oxidised to create new NAD+ during aerobic respiration, when it will be used once more in glycolysis.
Pyruvate will undergo oxidation in the absence of oxygen or if an organism is unable to engage in aerobic respiration.
Hence The most important reaction involved in the reoxidation of NADH is Pyruvate → lactate
