Answer:
Responsive.
Explanation:
HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.
Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of the HTML document contains the contents or informations of a web page to be displayed.
The responsiveness of a webpage is an ability of the design to respond to the end user's digital device and screen size.
In Computer programming, a responsive web design makes it possible for various websites to change layouts in accordance with the user's digital device and screen size.
This ultimately implies that, a responsive design is a strategic approach which enables websites to display or render properly with respect to the digital device and screen size of the user.
Hence, responsive webpages will automatically adjust the size of the content to display appropriately relative to the size of the screen of the device on which it is displayed.

The correct answer is B.
Explanation:

a) SELECT c.customer#, order#, orderdate, shipdate(omits aliases) FROM customers c NATURAL JOIN orders c(same aliases definiton);
c) SELECT c.customer#, order#, orderdate, shipdate(omits aliases) FROM customers c, orders c(same aliases definiton) WHERE c.customer# = o.customer#(o not declared);
