Answer:

B. Trans glycerophospholipids

Step-by-step explanation:

The answer turns out to be choice B, trans glycerophoslipids, because they "tend to increase the melting point of the membrane and therefore decrease membrane fluidity."

But wouldn't a trans molecule decrease fluidity instead? It would have a "kink" in it and decrease packing in the membrane, as opposed to the cis case.
