Concept:The answer is found by comparing the consonant sound of the underlined letter in the given word with the consonant sounds in the options.
Explanation:The given word is "zero", and the underlined letter "z" is pronounced as the voiced consonant sound /z/.
So, the option must contain the same /z/ sound.
Check the options one by one.
A. "days" is pronounced /deɪz/; the final letter "s" produces the /z/ sound.
B. "cease" is pronounced /siːs/; it has the sound /s/, not /z/.
C. "seizure" is pronounced /ˈsiːʒə/; the letter "z" here gives the /ʒ/ sound, not /z/.
D. "measure" is pronounced /ˈmeʒə/; the letter "s" gives the /ʒ/ sound, not /z/.
Only "days" has the same consonant sound /z/ as the underlined letter in "zero".
Answer:A. days
