    (a) saliva 6.2 - 7.4
    (b) bile 6.8 - 7.6
    (c) pancreatic juice 7.9 - 8.6
    (d) brunner gland secretion 8.1 - 9.3
    (e) Gastric juice 1.5 - 3.5

    ANS: (d) Brunner gland secretions
    In MCQs generally brunner gland secretion is not in the options, hence then the correct answer would be pancreatic juice
