Answer:
B
Step-by-step explanation:
While making any kind of necklace, it is advisable not to make many knots as they are difficult to untangle or undo later.
You should cut the string to the desired length first, leaving a bit of a margin to make a knot later. Then you make a loose knot at one end in order for the string to hold the beads properly. After you string the beads ( you can arrange them in any order you wish to ), you untie the loose knot ( that's why it had to be loose and not tight ), and you tie both ends of string together making a strong knot this time. Then you cut off the remaining pieces of string off the knot.
