What will be the output of this PowerShell code?

switch -Regex ('dog', 'cat', 'caterpillar') {
  '^cat' { 'Starts with cat' }
  'dog' { 'Exact dog' }
  default { 'No match' }
}

ANo match Starts with cat Starts with cat

BNo match Exact dog No match

CStarts with cat No match Starts with cat

DNo match No match No match

Step-by-Step Solution

Solution:

Step 1: Evaluate each input against regex patterns
Input 'dog': matches 'dog' pattern exactly? Yes, but order matters. The first pattern is '^cat' which does not match 'dog'. The second pattern 'dog' matches exactly, so output is 'Exact dog'.
Step 2: Check 'cat'
'cat' matches '^cat' pattern (starts with 'cat'), so output is 'Starts with cat'.
Step 3: Check 'caterpillar'
'caterpillar' also starts with 'cat', so matches '^cat' pattern, output 'Starts with cat'.
Step 4: Consider multiple matches
By default, switch -Regex processes all matching patterns per input. For 'dog', only 'dog' matches. For 'cat' and 'caterpillar', only '^cat' matches.
Final Answer:
No match Starts with cat Starts with cat -> Option A
