The novel guidelines issued by the board are intended to bringing up a major transformation in the corporate hierarchy.

The correct answer is bringing about.

Step-by-step Explanation:
To choose the correct replacement segment, we must analyze the contextual meaning of the phrasal verbs in the given sentence:

"The novel guidelines issued by the board are intended to bringing up a major transformation in the corporate hierarchy."

1. Contextual Analysis:
The sentence discusses guidelines that are designed to cause or lead to a major transformation. Therefore, we need a phrasal verb that means "to cause something to happen" or "to result in."

2. Meaning of the Phrasal Verbs:
• Bring about: Means to cause something to happen, produce, or initiate a major change or transformation. This fits the context of the sentence perfectly.
• Bring up: Means to raise a child or to introduce a topic for discussion, which does not fit the context.
• Bring in: Means to introduce a new product/law or to generate income/profit.
• Bring out: Means to publish, produce, or emphasize a specific quality.

Conclusion:
Replacing the underlined portion "bringing up" with bringing about provides the precise contextual meaning required for the sentence.
