C, 0.1 mol.

Explanation:

According to the periodic table, the molar mass of Ca is 40.1, C is 12.0, O is 16.0,

so the molar mass of CaCO3 is 40.1 + 12.0 + 16.0 x 3 = 100.1

Using this formula:

no. of moles = mass / molar mass

No. of moles of CaCO3 = 10 / 100.1

= 0.1 mol (corrected to 1 d. p.)

Therefore, the answer is C, 0.1 mol.
