To answer this question, let's go through each option to understand the correct sequence of releasing a transport and importing it to the subsequent system:
Option A) abc - According to this sequence, the technical approval of the revtrac by the programmer is first (a), followed by releasing all the relevant tasks (b), and finally, the functional approval of revtrac by the revtrac owner (c). However, this sequence is incorrect.
Option B) cba - According to this sequence, the functional approval of revtrac by the revtrac owner is first (c), followed by releasing all the relevant tasks (b), and finally, the technical approval of the revtrac by the programmer (a). However, this sequence is incorrect.
Option C) bac - According to this sequence, the release of all the relevant tasks is first (b), followed by the technical approval of the revtrac by the programmer (a), and finally, the functional approval of revtrac by the revtrac owner (c). This sequence is correct.
Option D) cab - According to this sequence, the functional approval of revtrac by the revtrac owner is first (c), followed by the technical approval of the revtrac by the programmer (a), and finally, releasing all the relevant tasks (b). However, this sequence is incorrect.
The correct answer is C) bac. This option is correct because it represents the correct sequence of releasing a transport and importing it to the subsequent system.
