Question 10

UKGAQUQU

Following the provided instructions step by step, the resulting letter sequence is UKGAQUQU after modifications.

A) CKGAQUQU

This option is incorrect because the first and last letters of the original sequence JCKGABBH, which are J and H, were not crossed out. Additionally, the letter B was replaced with Q, and a U was inserted after each Q, which this option does not reflect.

B) UKGAQUQU

This option is correct as it accurately reflects the sequence after applying all modifications: the first and last letters J and H are crossed out, B is replaced with Q, a U is added after the Q, and the first and last letters are switched.

C) HCKGAQUQ

This option is incorrect because it does not follow the prescribed instructions. The first and last letters J and H were not removed, and the letter B was not replaced with Q as required.

D) QKGAQUCJ

This option is incorrect as it fails to accurately reflect the instructions provided. The first and last letters J and H were not crossed out, and the replacement of B with Q has not been properly executed, leading to an incorrect sequence.

Conclusion

The correct answer, UKGAQUQU, is derived from carefully following each step of the instructions, showing that it is the only option that accurately matches the final sequence. All other options fail to adhere to the transformation rules outlined, thus confirming the validity of the correct answer.
