Consider the following record types:

TYPE $t1=$ RECORD $a,b$: INTEGER END

TYPE $t2=$ RECORD $i,j$: INTEGER END

Select the code fragment that would be LEGAL in a language with structural equivalence, but

NOT LEGAL in a language with name equivalence. $($The $...$ represent some legal way of

initializing the variable$)$

$t1x=$dots

$t2y=x$;

$t1x=$dots

$t1y=x$;

None of the other answers respond to the question as they are all legal in a language with name

equivalence.

$t1x=$dots

$t2x=$dots
