You would need to remove the endings such as -ar, -er, -ir and in this case change it to go to see if it makes sense
Here are the following:
Congo
Tengo
Repetgo
Vengo
Cerrgo
Hacgo
Lego
The ones that make sense are:
Tengo
Vengo
The others wouldn’t make sense with a -go ending
Therefore it is B and D
Tener and venir
Hope this helps! :3
