A Codebusters team uses data from previous events to build a letter frequency table. Which statement best describes how to use this table during a timed event?
-
A
Substitute the most frequent ciphertext letter directly for E without checking word patterns
-
B
Cross-reference frequency data with word length patterns and common word shapes to narrow substitutions
-
C
Ignore frequency data and rely entirely on guessing common words
-
D
Use frequency data only if the cipher has more than 200 characters
