print "Enter option (1, 2, 3): "
input = gets.chomp

if input == '1'
  puts "I'm executing option 1."
elsif input == '2'
  puts "I'm executing option 2."
elsif input == '3'
  puts "I'm executing option 3."
else
  puts "Bad input."
end


Or:

print "Enter option (1, 2, 3): "
input = gets.chomp

case input
when '1'
  puts "I'm executing option 1."
when '2'
  puts "I'm executing option 2."
when '3'
  puts "I'm executing option 3."
else
  puts "Bad input."
end
