Transact SQL :: Using Case Statement With Update Query

I have a table A  and lookup table B.

table A:
| ID | FRUIT | VEGETABLE | GOOD |
--------------------------------------------
|  1  | orange | cabbage     |  no   |
|  1  | apple  | lettuce        |  yes   |
|  1  | kiwi     | broccoli      |  no   |
|  1  | pear    | kale           |  yes   |

table B:
| ID | FRUIT | VEGETABLE |
-------------------------------
| 1  | apple  |  lettuce       |
| 2  | pear    |   kale         |

If the fruit and vegetable in table A is found in table B, then set the GOOD column = yes, else no.

This is what I have so far.

update tableA
set GOOD =
(case when tableA.id = C.id then 'yes'
else 'no'
end
)
from
(select tableA.id as id
from tableA A
left join tableB B on B.fruit = A.fruit
and B.vegetable = A.vegetable) C
