According to my calculations, C should be correct as 1.00 mole of any substance is 6.022 x 10^23 which is known as Avogadro's number.
Solution:[tex]Let the molar mass of metal M is 'a',\\
\rn(so)\\
\frac{M_{o}}{2M_{H}+2M_{o}+a} =\frac{2.16}{2.1+2.16+a} =0.328\\
By simple algebric calculation. We get,\\ a=63.56g/mol\\
\rn(Now,)\\
We have to confirm which metal has the molar mass of 63.56g/mol. By using periodic table we have to find it the we get it is Copper(Cu).

Answer:
Moles of NaOH that reacted: 
Explanation:
During the titration, all moles of NaOH added in the solution, react with the acetylsalicylic acid neutralizing each other.
The titration required 15.62 ml (0.01562 L) of the 0.1052 M NaOH solution. The moles of NaOH in that volume are:
