a) by the time they (who? birds? attacks? people?) had reached adulthood, 98 percent of men and 75 percent of women born in country have been attacked by the birds
b) by the time they (who? birds? attacks? people?) reach adulthood, 98 percent of men and 75 percent of women, who were born in the country, had been attacked (incorrect use of perfect tense) by birds.
c) by the time they correctly modifies the noun that immediately follows comma reach adulthood, 98 percent of men and 75 percent of the women born in the country had been attacked by the birds.
d) 98 percent of the men and 75 percent of the women that were born in the country were attacked by the birds by the time they (incorrectly modifies birds) reach adulthood.
e) 98 percent of men and 75 percent of women who were born in the country, by (illogical. try to replace the long noun with a simple word such as "people" and try to read the sentence from beginning till the end, and you will notice "study suggests that people, by the time they reached adulthood...."makes no sense) the time they reached adulthood had been attacked by birds 
 
Handy Trick: Replace a long wordy noun with a simpler one and re-read the whole sentence to avoid such mistakes.
