Concept:The underlined letters in the question represent the consonant sound /r/.
The correct option must contain the same /r/ sound.
Explanation:We check each option for the presence of the /r/ sound.
The word "balm" is pronounced /bɑːm/, so it has no /r/ sound.
The word "carry" is pronounced /ˈkæri/, and its double "rr" makes the /r/ sound.
The word "calcium" is pronounced /ˈkælsiəm/, so it contains no /r/ sound.
The word "psalm" is pronounced /sɑːm/, so it also has no /r/ sound.
Therefore, "carry" is the only word that shares the same consonant sound /r/ as the underlined letters.
Answer:B. carry
