Step-by-Step Solution:
Verification / Alternative check:
Given the options are compact 5-digit forms, compare their patterns against the left-to-right decoding. The only candidate preserving the order 7-9-3-8-2 after removing the repeated initial “9” is 79382, which matches the intended reading across the distinct symbols.
Why Other Options Are Wrong:
