The correct options are
B birthday cake
D candles
Options A and B: Nouns are words that name people, things, places,
animals, etc. Compound nouns are nouns made up of two or more words.
In the given sentence, 'birthday cake' is a compound noun that names 'a cake made for one's birthday'.
'Candles' names a 'block of wax with a wick that is burnt to produce light'.
Hence these are nouns and options A and B are correct.
Options C and D: 'There' is an adverb of place, since it points towards a direction of place.
'That' is a determiner that refers to a person or thing away from the speaker.
These words are not nouns and hence both options are wrong.
