  • changed
  • has changed
  • is changed
Show Solution

The Correct Option is C

Solution and Explanation

Step 1: Learn the tense rule for since.
The word since always pairs with the present perfect tense, has or have plus the past participle, when we talk about a change or state that began earlier and continues to affect the present.

Step 2: Check each option against this rule.
is changing is present continuous, changed is simple past, is changed is an odd passive-like form; none of these pair correctly with since. Only has changed is the true present perfect form.

Step 3: Plug it into the sentence.
"The man has changed his appearance completely since then" reads correctly and matches standard English grammar.

Final Answer:
Since demands the present perfect, so has changed is correct. $$ \boxed{\text{has changed, option C}} $$
