Hint – Angstrom is another form of meter as $1{A^o} = 1 \times {10^{ - 10}}m$ it is used to measure or express very smaller lengths such as one-tenth millions of a meter so use this concept to reach the solution of the question.
Complete step-by-step answer:
As we know that the symbol of Angstrom is ${A^o}$.
And we all know that Angstrom is the another form of meter which is given as
$1{A^o} = 1 \times {10^{ - 10}}m$
Now as we know meters are used to express the length.
So meter is the unit of length.
So Angstrom is also a unit of length.
But Angstrom is used to express very small length.
So Angstrom is a unit used to express the length.
This unit is also used to express the sizes of atoms, molecules, lengths of the chemical bonds, wavelength of electromagnetic waves etc.
This is not a standard S.I unit it is named after the Swedish physicist Anders Jonas Angstrom.
Anders Jonas Angstrom was well known for the field of spectroscopy (i.e. interaction between the matter and the electromagnetic radiation).
This unit is used extensively in chemistry as well as in physics but rarely in mathematics.
So this is the required answer.
Hence option (A) is the correct answer.
Note – The Angstrom is a metric unit of length equal to ${10^{ - 10}}$m i.e. one ten-billionth of a meter, 0.1 nanometer, or 100 pedometers. Its symbol is ${A^o}$, a letter of the Swedish alphabet. The Angstrom is not a part of the SI system of units, but it can be considered part of the metric system in general.
