Option B uses By.PARTIAL_LINK_TEXT with the exact substring "Learn" which matches part of the link text.
Option B requires the full link text to be exactly "Learn" which is unlikely.
Option B uses lowercase "learn" which is case sensitive and will not match "Learn".
Option B uses CSS selector which matches href attribute, not visible link text.
<a href='/home'>Home Page</a> <a href='/learn'>Learn Selenium</a> <a href='/contact'>Contact Us</a>
What will be the text of the element found by:
element = driver.find_element(By.PARTIAL_LINK_TEXT, "Learn") print(element.text)
The link with text "Learn Selenium" contains the substring "Learn" so it is found and printed.
Other links do not contain "Learn".
element = driver.find_element(By.PARTIAL_LINK_TEXT, "Docs")Option C asserts the element is visible on the page, which confirms presence.
Option C fails if the link text is longer than "Docs" (e.g., "Documentation").
Option C incorrectly compares href attribute to "Docs" string.
Option C asserts element is None which is false if element is found.
element = driver.find_element(By.PARTIAL_LINK_TEXT, "help")
But it raises NoSuchElementException even though the page has a link with text "Help Center". What is the most likely cause?
Partial link text matching is case sensitive, so "help" does not match "Help".
Option D is false because partial link text matches any substring.
Option D is false; spaces are allowed.
Option D could cause failure but question states the link is on the page, so less likely.
Option A waits for presence of element located by partial link text "Start" which is correct.
Option A uses full link text locator which may fail if text is longer.
Option A uses lowercase "start" which is case sensitive and may fail.
Option A uses invalid CSS selector syntax; :contains is not supported.
