When Alaska passed a law in the 1970s that gave state residents preference over nonresidents in obtaining work on oil pipelines, this law violated the clause.

The correct answer is privileges and immunities clause.

Explanation:

This clause of the second section requires interstate protection of "privileges and immunities." The ambiguity of the clause has given rise to different interpretations.

Others suggested that citizens of a state, when traveling to different states, transfer the rights recognized by their states of origin. None of these theories have been accepted by the Supreme Court which, on the other hand, has stated that the clause means that states cannot discriminate against citizens of other states in favor of their own citizens.
