Which subatomic particle listed below has the least mass?

new info for me.thanks

AdeShake, true but it's not one of the listed answered.

AdeShake, Thank you for pointing this out.

babayaga69, This answer is just plain wrong. The neutrino is the lightest of all sub-atomic particles being at the very least 500,000 times lighter than an electron and possibly up to 6,000,000 times lighter according to various research institutions around the world.

that one made me think😉
