Answer 1

The correct option is (a) Tokens Explanation: The string returned by the network layer gets tokenized into meaningful chunks. The rendering engine then takes the tokens and converts them to DOM elements. There are five categories of tokens: 1) constants, 2) identifiers, 3) operators, 4) separators, and 5) reserved words.
