In the following question, four words are marked with letters (A), (B), (C), and (D), which may not be in their correct positions. Select the option that indicates the correct pair(s) of words to be interchanged to make the sentence grammatically correct and coherent.

Although Sarah was initially hired for deeply (A), she grew management (B) interested in botany and resolved to research (C) all her previous abandon (D).

The correct option is Only (A)-(B) and (C)-(D).

To make the sentence grammatically correct and coherent, let's analyze the highlighted words in context:

1. Interchange between (A) and (B):
- In the phrase "hired for deeply (A)", the preposition "for" requires a noun object. Therefore, "management" should be placed at position (A).
- In the phrase "she grew management (B) interested", the adjective "interested" requires an adverb modifier. Therefore, "deeply" should be placed at position (B).
Interchanging (A) deeply and (B) management yields: "hired for management, she grew deeply interested..."

2. Interchange between (C) and (D):
- Following "resolved to", an infinitive verb is required, making "abandon" appropriate for position (C).
- After the modifier "all her previous", a noun is required, making "research" appropriate for position (D).
Interchanging (C) research and (D) abandon yields: "...and resolved to abandon all her previous research."

Corrected Sentence:
"Although Sarah was initially hired for management, she grew deeply interested in botany and resolved to abandon all her previous research."
