How to ride no handed on a bike
Try riding one-handed with each hand.
You may find that one hand is easier to ride with than the other. If you practice enough it will become easier.

Available options: a. Be sure to always consult your instructor to see if using both hands is a viable solution. Learn to hold a hand snug to the handlebars and wrap your fingers around them.; b. Once you get the hang of riding one handed, try taking your hands off of the handlebars for a few seconds at a time. Keep them close so you can grab the bars again and not fall if you get nervous.; c. Lift your right foot and lift your left foot higher so that your foot is flat at waist level. The balance of the foot will be impossible and it will experience a lot of force that can then wear down the bike.; d. Do not change this hand position too often or use a lot of push ups. This is because you want a less jarring impact on your body than gripping the handlebars with one hand.;
The answer is:
b.
