Question Deleting lines from file using another file

I am having a requirement like
File A contains All the records

Code:
ONE
TWO
THREE
FOUR
FIVE
SIX
SEVEN
EIGHT
NINE
TEN

File B contains invalid records of File A
eg.,
Code:

NINE

Is there any sed or awk command to be used in shell script to compare files A and B and filtered out only good records in A.

Basically I need to delete all the lines in A which are present in B.
My final A file should be like
