Drop all symbols first, then re-write the remaining alphanumeric characters in order and simply count from the right side.
Filter the series
Given series: 2, 7, &, 3, Ω, 9, #, 1, *, £, &, %, 4, 6, @, 8, , 5. \text{Removing} all symbols (&, Ω, #, *, £, &, \%, @, ) leaves: 2, 7, 3, 9, 1, 4, 6, 8, 5.
Count from the right
The new series is: 2, 7, 3, 9, 1, 4, 6, 8, 5. Counting from the right (last element is 1st): 1st is 5, 2nd is 8, 3rd is 6, 4th is 4, 5th is 1.
A: Represents the 2nd from the right, which is 8; B: Represents the 3rd from the right, which is 6; D: Represents the 4th from the right, which is 4.
C is correct because after removing the symbols, the resulting sequence is 2, 7, 3, 9, 1, 4, 6, 8, 5, and the fifth element counting from the right end (5, 8, 6, 4, 1) is 1.
When asked to 'drop' items, always strike them out on your rough sheet first to avoid parallax errors during counting.
