Correct Answer: Twinkle

Solution : Given:
Twinkle, Twister, Trump, Trigger

Step 1: Compare the first letter of each word. Since all the words start with the same letter T , move to the next letter.
Step 2: The second letters of the words are w, w, r, r in the given order of the words. Based on the alphabetical order of these letters, the order of the words will be T r ump, T r igger, T w inkle, T w ister
Step 3: Compare the third letter of (Tr u mp, Tr i gger). Trigger will come before Trump in the sequence as i comes before u in the alphabetical order.
Step 4: Compare the fourth letter of (Twi n kle, Twi s ter). Twinkle will come before Twister in the sequence as n comes before s in the alphabetical order.
So, the sequence will be Trigger, Trump, Twinkle, Twister.

Therefore, the word Twinkle appears third in the sequence. Hence, the first option is correct.
