Which of the following colligative properties can provide the molar mass of proteins (or polymers or colloids) with greater precision?

Which of the following statements is incorrect?

$A$ wire of length $l$ is bent into a circular loop of radius $R$ and carries a current $I$. The magnetic field at the centre of the loop is $B$. The same wire is now bent into a double loop of equal radii. If both loops carry the same current $I$ and it is in the same direction,the magnetic field at the centre of the double loop will be
