Explanation / Answer

Q3)

POSITIVE CORRELATION MEANS THAT AS THE VALUUE OF ONE VARIABLE INCREASES, SO DOES THE VALUE OF OTHER VARIABLE.

=> OPTION : 'A'

Q4)

IN NEGATIVE CORRELATION, AS VALUE OF ONE VARIABLE INCREASES, VALUE OF OTHER DECREASES OR VICE VERSA.

IN THE OPTION "D", AS THE NUMBER OF IMMUNIZATION UPTAKE IS INCREASING, THE INCIDENCE OF MEASELS ILLNESS IS DECREASING. I.E., BOTH ARE MOVING IN OPPOSITE DIRECTION.

HENCE, OPTION "D" IS GOOD EXAMPLE FOR NEGATIVE CORRELATION.
