be welcome to
可以自由[随意}]
be popular with
受...欢迎

be welcomed 与be popular有什么区别

if you wanna express 受欢迎的 then choose B: popular

谢谢你的问题补充,确实是个难点,我补充一些答案你参考一下:
welcome VS. welcomed
1,He is not welcome in China
2,He is not welcomed in China

1,He is not welcome in China
=If he is planning to come to China he would not be welcomed

2,He is not welcomed in China
=when he already in China he receives no welcome from the people there

So you could see the difference,thanks.
