Answer:
a map
Explanation:
The sentence says: I use a map to navigate (or to cross)
The way you wrote those options, it would seem that none of them are correct. You can eliminate A and C immediately, because in A, the infinitive form of the verb salir is used (when you should use the present form), and in C, the form salis refers to vosotros/vosotras, not to ellos.
This means that the correct answer has to be B, but you've misspelled sales - it should be saleN. If that is the case, then you should definitely choose B.

Remember that the impersonal forms are those that do not coincide in <u>gender</u> and <u>number</u> with the subject that performs the action.

- Gerund
- Participle ⇢ In this case.
Remember that the participle is a <u>verbal form</u> while an adjective always <u>describes a quality of the noun</u>, always agreeing in gender and number with the noun it accompanies.
