Ok . I would go with option D .

Cause they have just mentioned dat x and y are decimals.

We do not know whether they are positv negative . Either which way let us take a few cases .

Case 1 :

If x = 0.007 and y = 0.0001

-》 x + y = 0.0071

X + y rounded to the hundredth placs it gives 0.007 which is x

Hence x = 0.007

You can choose option (C)

Case 2 :

X = 0.006 and y = 0.0001

X+y = 0.0061

Rounded off gives 0.006 which is = x

Hence you could choose option (B)

With jus two cases we get varying answers.

So we need more info to know what precise values of x and y are we allowed to take .

Hence d qns would be option (D)

Hope dis helped.

Kudos plz if it did :D
