What is the value of $1m$ in $\mathring{A}$?

The correct option is D ${10}^{10}$

$1m={10}^{10}\mathring{A}$

or we can say 1 angstrom $={10}^{-10}m$

The natural sciences and technology often uses angstrom to express sizes of atoms, molecules, microscopic biological structures, and lengths of chemical bonds, arrangement of atoms in crystals, wavelengths of electromagnetic radiation.
