i guess it's D . the because of the noun "lives" . But however , I'm not sure because in some case , we can use "the" even though there is a plural noun after it .
Am i right ?

D is wrong, but 'lives' is no problem. 'The' is inappropriate because 'people' have already been mentioned. It should read 'their lives'.

According to my guess B) will be the correct answer. Because it gives the continuation of that sentence.
