Query: $b\to cl\nu$ anomalies in light of vector and scalar interactions   We perform a model independent analysis of the charged current $b\to cl\nu$
anomalies under the presence of scalar and vector interactions. The analysis is
carried out in two stages: (a) under the presence of both (left-handed) vector
and scalar interactions and (b) under the presence of scalar interactions
alone. We find that even after stringent bounds from similar quark-level
processes such as $B_c\to\tau\nu$, such scenarios have the potential to explain
the aforementioned anomalies. Contrary to the general notion, we show that even
scalar interactions alone can explain such anomalies, provided they are
complex. However, extended scalar sector models are unable to comply with these
anomalies to $\sim 3\sigma$. We further illustrate our results with the help of
three benchmark models corresponding to the presence of (i) both scalar and
vector (ii) real scalar and (iii) complex scalar interactions.
