  4. D

Answer

crew's findings depended on its
The correct option correctly pairs the singular determiner 'each' with the singular possessive 'crew's' and uses the possessive pronoun 'its' to modify 'sonar array'.

Step-by-Step Solution

1
Determine whether the noun 'crew' should be singular or plural.
The noun must be singular ('crew') because it is modified by the singular determiner 'each'.
The determiner 'each' always precedes singular countable nouns in this context.
2
Determine the correct possessive form for the singular noun 'crew'.
The correct form is 'crew's'.
Singular possessive nouns are formed by adding an apostrophe followed by 's'.
3
Determine whether to use the possessive pronoun 'its' or the contraction 'it's' to modify 'sonar array'.
The correct word is the possessive pronoun 'its'.
The sentence requires a possessive relationship for the sonar array. The contraction 'it's' stands for 'it is' or 'it has' and is grammatically incorrect here.
