Answer:
B. Both sets contain the same elements.
Explanation:
Given:
A={The letters in the word SEAT}
B={The letters in the word TASTE}
Writing the sets in elements form
A = {S,E,A,T}
B={A,S,T,E} => the letter T appears two times but the repeating elements are written only once.
Hence, both sets contain the same letters.
Therefore, the correct answer is:
B. Both sets contain the same elements ..
