Given a string s="Welcome", which of the following code is incorrect ?

एक स्ट्रिंग s="Welcome" दी गई है, निम्नलिखित में से कौन सा कोड गलत है?

print s[0]

print s.lower()

s[1]='r'

print s.strip()

Explanation:

Here’s a quick breakdown:

(A) s[0] is correct; it prints the first character "W".
(B) s.lower() is correct; it converts the string to "welcome".
(C) s[1] = 'r' is incorrect because strings are immutable in Python (you can't change individual characters).
(D) s.strip() is correct; it removes any leading or trailing spaces (if any).

(C) s[1] = 'r' is incorrect.
