Odd Number/Letter from the Given Alternatives

To find the odd number/letter from the given alternatives, we need to carefully examine each option and identify the one that does not fit the pattern or sequence. Let's analyze each option one by one:

a) XWVU
b) SRQP
c) SRQM
d) EDCA

Analyzing the Options:

a) XWVU: This option consists of letters in descending order, starting from 'X' and ending with 'U'. Each letter is one step lower in the alphabet compared to the previous one. This pattern follows a reverse alphabetical order.

b) SRQP: Similar to option a), this option also consists of letters in descending order. The letters 'S', 'R', 'Q', and 'P' follow a reverse alphabetical pattern.

c) SRQM: This option appears similar to option b), with the letters 'S', 'R', 'Q'. However, the last letter 'M' breaks the pattern. Therefore, this option does not follow the same sequence as the previous options.

d) EDCA: This option consists of letters in descending order, starting from 'E' and ending with 'A'. Each letter is one step lower in the alphabet compared to the previous one. This pattern follows a reverse alphabetical order, similar to option a).

Identifying the Odd Option:

After analyzing each option, we can conclude that option c) SRQM is the odd option. It does not follow the same pattern as the other options.

Conclusion:

The odd number/letter from the given alternatives is option c) SRQM.
