#TFQOD Check out our CAT Question Of the Day. Watch this space for the solution tomorrow. Arrange the given sentences in the most logical sequence. A. A research group led by an NIST physicist unveiled the experimental strontium atomic clock that has set new world records for both precision and stability - key metrics for the performance of a clock. B. Precision refers to how closely the clock approaches the true resonant frequency at which its reference atoms oscillate between two electronic energy levels. C. The strontium lattice clock is 50 per cent more accurate than the previous record holder, the National Institute of Standards and Technology (NIST) quantum logic clock. D. Scientists claim to have developed a new record-breaking atomic clock that is so precise that it neither loses nor gains a second in five billion years - longer than the age of the Earth. OPTIONS 1) ABCD 2) DCAB 3) ACBD 4) DACB
