Question

6- guys, cmon, its a multiple choice question. do you have like a personal vendetta against me to keep rejecting the question? just look at the pic and answer the multiple choice question please or else imma cry

Figure 13B-3 displays the vertical profiles of temperature (°C) and salinity (dissolved salt in psu, or practical salinity units) acquired by Float 6901566 during its 169th
cycle, ascending from about 2000 dbar (decibar) to the ocean surface on 5 January 2019. [Recall from Investigation 3A that ocean water 1 m in depth exerts a pressure of
1 dbar. Consequently, a decibar pressure scale is numerically equivalent to water depth in meters. For the purposes of this investigation, the vertical scale of graphed
profiles will be discussed in meters depth. In the ascent just described, the float rose from a depth of 2000 m.]
