Answer: Kepler-438b (Please thank One-Eye below. :T :T :T)

I think it might be Kepler-438b - just checking further.

Earth Similarity Index (ESI) (closest to 1 is the most Earth-like)
Kepler-438b = 0.88
Gliese-667Cc = 0.84
Kepler-442b = 0.83
Kepler-452b=0.83

answer = Kepler-438b

Kepler 452b

The new planet, named Kepler 452b, is “the closest twin to Earth, or the Earth 2.0 that we’ve found so far in the dataset”, said John Grunsfeld, associate administrator for Nasa’s mission directorate.
“This is the first possibly rocky, habitable planet around a solar-type star,” said Jeff Coughlin, a Seti scientist. All 11 previously discovered exoplanets of a similar size and orbit travel around stars that are smaller and cooler than the sun.
“It is the closest thing that we have to another place that somebody might call home,” said Jon Jenkins, a Nasa scientist. The planet is like Earth’s “older, bigger first cousin”, he said.

This is dated 23rd July 2015

Kepler 438b was discovered in Jan 1015 http://www.theguardian.com/science/2015/jan/06/earth-like-planet-alien-life-kepler-438b
At the time it was called "Most Earth-like planet ever discovered"

But as Kepler 452b was discovered after Kepler 438b and called "the closest twin to Earth, or the Earth 2.0 that we’ve found so far in the dataset" by John Grunsfeld, associate administrator for Nasa’s mission directorate I am going with Kepler 452b as I'm assuming John Grunsfeld isn't telling fibs.

Thank you - no doubt this is correct, but there are 3 answers to choose from and this isn't one of them. They are:

A: Gliese 667 Cc
B: Kepler-438b
C: Kepler-442b

How odd, they must have changed it the answer options from last night
