Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
The angstrom or angstrom is a metric unit of length equal to 10-10 m; that is, one ten-billionth of a metre, 0.1 nanometre, or 100 picometres. Its symbol is Å, a letter of the Swedish alphabet. The angstrom is not a part of the SI system of units, but it can be…
