The following question gives a sentence which has been divided into four parts which may not be in their correct order of narrative. The sentence is then followed by five options, one of which gives the sequence of the rearranged parts to make the sentence meaningful. Choose the option which gives the correct sequence of the parts. If the sentence is already arranged in the correct sequence, mark option " No rearrangement required " as the answer.

The correct option is DCBA.

To find the correct order of the given sentence parts, let us analyze each part logical and grammatically:

Part (D): "butterflies taste their"
This part introduces the subject ("butterflies") and action ("taste their"). Since "their" is a possessive pronoun, it must be followed by a noun that belongs to them.

Part (C): "food with their feet,"
This part provides the noun "food" that completes "taste their food", along with the prepositional phrase "with their feet," specifying how they do it.

Part (B): "as their taste sensors"
This clause explains why they can taste food with their feet, introducing the noun phrase "their taste sensors" as the subject of the next clause.

Part (A): "are located in their legs"
This part contains the verb phrase "are located in their legs", completing the thought started in Part (B) by explaining where the taste sensors are situated.

Putting it all together, the complete and meaningful sentence is:
"Butterflies taste their food with their feet, as their taste sensors are located in their legs."

Thus, the correct sequence of the sentence parts is D - C - B - A.
