What is the result of the following code?

data $,$ index$=[\text{'}$a$\text{'},\text{'}$b$\text{'},\text{'}$c$\text{'},\text{'}$d$\text{'}])$

data$[\text{'}$a$\text{'}$:$\text{'}$c$\text{'}]$

The values associated with $\text{'}$a$\text{'}$ and $\text{'}$b$\text{'}$ only

Only the value associated with $\text{'}$a$\text{'}$

An error, as the slicing is incorrect

The values associated with $\text{'}a\text{'},\text{'}b\text{'},$ and $\text{'}c\text{'}$
