Hi there, A is correct - This kind of instant noodles is delicious!

I think A is correct. Because the subject is "this kind" but not "noodles" and it is singular.

These kinds of noodles are delicious. This kind of noodle is delicious.

Neither is correct, the answer should be “these kind of noodles are delicious”- as “noodles” is plural you need “these” rather than “this”. 加油！

The sentence should read "These kinds are noodles are delicious" or "This kind of noodle is delicious"
