Correct Answer: 2, 3, 5, 1, 4

Solution : Given:
1. Sandwich 2. Salad 3. Salami 4. Saturn 5. Salty

Step 1: Compare the first and the second letter of each word. Since all the words start with the same letter S and are followed by a, then move on to the next letter.
Step 2: The third letter of each word is l , n , or t. Based on the alphabetical order of these letters, we can arrange them – Sa l ad, Sa l ami, Sa l ty, Sa n dwich, Sa t urn.
Step 3: Compare the fourth letter of (Sal a d, Sal a mi, Sal t y). Sal a d, and Sal a mi will come before Sal t y in the sequence as a comes before t in the alphabetical system.
Step 4: Compare the fifth letter of (Sala d , Sala m i). Sala d will come before Sala m i in the sequence as d comes before m in the alphabetical system.

So, the sequence is Salad, Salami, Salty, Sandwich, Saturn or 2, 3, 5,1, 4. Hence, the first option is correct.
