What is the correct sequence in which lengths of the following units increase? 1. Angstrom 2. Micron 3. Nanometer Select the correct answer using the code given below:

The correct sequence in increasing order of length is Angstrom, Nanometer, and Micron. An Angstrom (Å) is a non-SI unit of length equal to 10⁻¹⁰ meters or 0.1 nanometers [t1][t6]. A Nanometer (nm) is a metric unit equal to 10⁻⁹ meters, meaning there are 10 Angstroms in one nanometer [t1][t4]. A Micron (micrometer, µm) is a larger unit equal to 10⁻⁶ meters or 0.001 millimeters [c3]. In terms of relative scale, 1 Micron equals 1,000 Nanometers or 10,000 Angstroms [t3]. Therefore, the units follow the progression: 1 Angstrom (10⁻¹⁰ m) < 1 Nanometer (10⁻⁹ m) < 1 Micron (10⁻⁶ m). This corresponds to the sequence 1, 3, 2 as provided in the options.
